TYPE. RSTS/E supports the use of '?' to match any single character, whereas the others use a '%' to match any single character. The RSTS/E Kermit server will translate '%' to '?' internally for the GET and REMOTE DIR commands (see chapter on the SERVER). .s 1 Examples of wildcarded filenames: .lit *.B2S match any file with a TYPE of B2S K11%%%.MAC match any file starting with K11, followed by one to three characters, with a TYPE of MAC K11???.MAC Same as above, but for RSTS/E only. XYZ.*;* All versions of files with a NAME of XYZ with any TYPE (RSX-11M/M+ and P/OS only). .eli .index File formats (binary and text) File formats (binary and text) .s 1 RT-11 and TSX+ .s 1 RT-11 treats all files as a contiguous stream of characters. There is no information stored in the directory to tell the system (or program) that a file is readable text (source program, runoff document,...) or consists of binary data (executable program, object file, .SYS file,...). An application program like Kermit-11 needs to know what type of file to expect, thus the presence of the SET FILE TYPE command (discussed later). The only real convention is that text files are streams of seven bit data with each record terminated by a carriage return/line feed character sequence and that binary files normally follow a filename TYPE convention. The TYPE (.SAV, .SYS, ...) is what Kermit-11 will look at to decide if a file should be sent as a text or binary file. .s 1 RSTS/E, P/OS and RSX-11M/M+ .s 1 These systems can provide for a large number of file attributes for each file by using either FCS11 (RSX-11M/M+) or RMS11 (all). Text files are normally considered to be either STREAM format (FB$STM) or VARIABLE with implied carriage control (FB$VAR and FB$CR). RSTS/E has historically defaulted to STREAM, whereas the RSX based systems use VARIABLE. Kermit-11 follows those defaults when creating files unless told to do so otherwise by the presence of attribute data. The conversion of the internal data representation to one that can be transmitted to another Kermit is transparent for these types of files. Both the file attributes and the filename TYPE are examined by Kermit-11 to determine if a file needs to be sent as a text file (default) or a binary file. Additionally, on RSTS/E Kermit checks the file protection code, as one of the bits in it is used to flag an executable file (bit 6). .s 1 In all cases, unless (at this time) Kermit-11 is talking to another Kermit-11, or if Kermit-11 can't tell if a file is consists of binary data, the command SET FILE TYPE FIXED must be used to force Kermit to either send or get a non-text file correctly. When Kermit-11 is running in binary mode, all data is read from (or written to) the file without any translation or internal record control information. Any attribute information in the file's directory entry is ignored and the data read (or written) in 512 byte unformatted blocks. Thus it is indeed possible to transfer files like task images and object libraries. Since Kermit-11 supports a subset of a protocol feature called 'attributes', two Kermit-11's connected together can also correctly transfer files other than simple text and unformatted binary files, such as RMS indexed or relative files. .s 1 .index Saving files on the PDP-11 from your microcomputer Saving files on the PDP-11 from your microcomputer .s 1 You can send textual files to Kermit-11 without any special considerations as Kermit-11 defaults to creating normal text files. However, if you are sending a binary file (perhaps an EXE) from say, your Rainbow under MSDOS, you would need to tell Kermit-11 to expect binary data. This is done with the Kermit-11 command SET FILE TYPE FIXED. This will force Kermit-11 to write the data out exactly as it comes, in 512 byte unformatted records. Sending the same file back to the Rainbow would not require any special action since the file, as it sits on the PDP-11, has the proper information in the directory entry to tell Kermit-11 that theK11USRRNO[.050032]K11USR.RNO[.050032]    X14|H [4;Ik(&'( k ߫H&P` \RrPP2PPzPP{PPPPP2P~\$\\TD 0D \~ hi) +\ ^( n ^( np\^txY\^ˀ\!kVk<\F˰<˴ˬ\VVkˤ1`@lP ABCDEFGHIJKLMNOPQRSTUVWXYZ$.?0123456789<@<SЬTЬ UQS>?\\\\\\\\\`:#@'="\abcdefghi\\\\\\\jklmnopqr\\\\\\\~stuvwxyz\\\\\\\\\\\\\\\\\\\\\\{ABCDEFGHI\\\\\\}JKLMNOPQR\\\\\\\\STUVWXYZ\\\\\\0123456789\\\\\  !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`ABCDEFGHIJKLMNOPQRSTUVWXYZ{|}~@ggh<i|o<m<4p<p<k|Zn<l fr rwx<x<x<x޺<w@]@@fjnr]Ze@@|> | |v<H|  |  |xz|  |zt f r   < &^ @&@'*/V,"?Lh:hmBmz|z{x`y~|fN|@@|@͂|@ ݃ƃ<ns<|Ŏ |️|ep|u|-@率|<ﾲ2ֻr||ZRM | ntB|xyvZw|J=|R>|J? nnaa|bddf by both interface type (DL11 vs DZ11) and by operating system, Kermit-11 makes NO attempt to find out what the current parity of it's line is.

On RSTS/E lines are often made unaccessible unless your account possesses the needed privilege(s). On RSX-11M/M+, privilege is required to alter settings on any other terminal line. You may have to talk to your system manager to get access to an outgoing terminal line. .s 1 Once connected to a modem through another line, a means must exist for the connection to be broken (if the host you are calling won't do it). Given that your line has full or partial modem control (DZV11, DZ11, DH11, DHU/V11) the RSX, RT-11/TSX+ and RSTS/E Kermits have a HANGUP (or DISCONNECT) command, which instructs the system to disconnect the modem. Unless this is done, you never get disconnected and could run up a tidy phone bill. .lm 0 .s 1 .subtitle Command line editing .s 1 Kermit-11 has, as of v3.53, a rudimentary command line editor. You can recall previous commands with the UP-Arrow key, and exit the command with the LEFT and RIGHT arrow keys.

If filespec contains wildcard characters then all matching files will be sent, in alphabetical order (according to the ASCII collating sequence) by name. If filespec does not contain any wildcard characters, then the single file specified by filespec will be sent. .s 2 SEND Command General Operation: .s 1 Files will be sent with their PDP-11 file name and type (for instance FOO.BAR). Each file will be sent according to the record type and attributes recorded in its file descriptor. Kermit-11 attempts to translate all formats of text file to a format usable on any system. Note that there is no need to set the FILE TYPE parameter for sending files, since Kermit-11 always uses the information from the file directory entry and the filetype (extension) to determine how to send the file. .s 1 If communication line parity is being used (see SET PARITY), Kermit-11 will request that the other K11USRRNO[.050032]K11USR.RNO[.050032]    X14|H [4;Ik(&'( k ߫H&P` \RrPP2PPzPP{PPPPP2P~\$\\TD 0D \~ hi) +\ ^( n ^( np\^txY\^ˀ\!kVk<\F˰<˴ˬ\VVkˤ1`@lP ABCDEFGHIJKLMNOPQRSTUVWXYZ$.?0123456789<@<SЬTЬ UQS>?\\\\\\\\\`:#@'="\abcdefghi\\\\\\\jklmnopqr\\\\\\\~stuvwxyz\\\\\\\\\\\\\\\\\\\\\\{ABCDEFGHI\\\\\\}JKLMNOPQR\\\\\\\\STUVWXYZ\\\\\\0123456789\\\\\  !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`ABCDEFGHIJKLMNOPQRSTUVWXYZ{|}~@ggh<i|o<m<4p<p<k|Zn<l fr rwx<x<x<x޺<w@]@@fjnr]Ze@@|> | |v<H|  |  |xz|  |zt f r   < &^ @&@'*/V,"?Lh:hmBmz|z{x`y~|fN|@@|@͂|@ ݃ƃ<ns<|Ŏ |️|ep|u|-@率|<ﾲ2ֻr||ZRM | ntB|xyvZw|J=|R>|J? nnaa|bddfand escaped back to the PDP-11. .s 1 The remote filespec is any string that can be a legal file specification for the remote system; it is not parsed or validated locally.

The Kermit-11 server is capable (as of this writing) of executing the following remote server commands: SEND, GET, FINISH, BYE, REMOTE DIRECTORY, REMOTE CWD, REMOTE SPACE, REMOTE DELETE, REMOTE TYPE, REMOTE HELP, REMOTE COPY, REMOTE RENAME, REMOTE WHO, REMOTE LOGIN and REMOTE HOST. .s 1 Any nonstandard parameters should be selected with SET commands before putting Kermit-11 into server mode, in particular the file type. The Kermit-11 server can send all files in the correct manner automatically. As noted before, if a Kermit-11 is talking to another Kermit-11, they will negotiate any 'binary' parameters automatically. However, if this is NOT the case and you need to ask Kermit-11 to receive binary files you must issue the SET FILE TYPE FIX command before putting it into server mode, and then you must only send binary files. You cannot send a mixture of text files and 8-bit binary files to a Kermit-11 server unless the files are not for use on the PDP-11. .s 1 .index Commands for Servers .center;Command for Servers .s 1 When running in local mode, Kermit-11 allows you to give a wide range of commands to a remote Kermit server, with no guarantee the that the remote server can process them, since they are all optional features of the protocol. Commands for servers include the standard SEND, GET, BYE, FINISH commands, as well as the REMOTE command. .s 1 .s 1 .index BYE The BYE command .s 1 The BYE command tells a remote server to log out of the remote system. In addition, some remote systems will also disconnect the line for you. If this is not the case, the DISCONNECT command will (depending on your interface) cause the line to be dropped. See DISCONNECT. .s 1 .index FINISH The FINISH command .s 1 The FINISH command tells the remote Kermit server to exit without logging out of the remote system. You can then CONNECT back to the system. .s 1 .index REMOTE REMOTE command .s 1 Send the specified command to the remote server. If the server does not understand the command (all of these commands are optional features of the Kermit protocol), it will reply with a message like "Unknown Kermit server command". If does understand, it will send the results back, and they will be displayed on the screen. The REMOTE commands are: .s 1 REMOTE COPY filespec newfilespec .s 1 .lm 5 Copy file. The server is asked to make a copy of the specified file. Both filespecs must be in the correct format for the remote system. Kermit-11 does not parse or validate the file specifications. Any leading spaces will be stripped and lower case characters converted to upper case. Note that this command simply provides for copying a file within the server's system - it does not cause a file to be transferred. .lm 0 .s 1 REMOTE CWD directory .s 1 .lm 5 Change Working Directory.

This command does not ensure that the desired type of block check will be used, since both Kermit's involved in the transfer must agree on the block check type. Kermit-11 will request that the type of block check set by this command be used for a transfer. If the other Kermit has also had the same block check type requested, then the desired block check type will be used. Otherwise, the single character checksum will be used. The command should be given to BOTH Kermits since Kermit-11, when in server mode, has no say about what kind of checksum it wants to use.

Note that binary files which are generated on a PDP-11 system cannot be transferred to another (non PDP-11) system without losing file attributes. This means that (for example), an RSM11 indexed file cannot be transmitted with Kermit-11 at this time. You can not have parity set to anything but NONE to use binary file transfer (see HELP SET PARITY) unless the other Kermit can process eight bit quoting. Two Kermit-11's connected to each other will use binary transmission automatically via the Kermit attribute packets, preserving file attributes where it makes sense (ie, RSTS/E and RSX only). .s 1 SET FILE TYPE DEC_MULTINATIONAL .s 1 PDP-11 Kermit normally strips the high bit of every character on both transmission and reception of files (unless the SET FILE TYPE FIXED command was given). The SET FIL DEC command will cause Kermit-11 to leave all data intact but still obey the host file system when reading or writing files. In other words, Kermit will write sequential implied carriage control files with eight bit data if this command is used. .s 1 SET FILE TYPE FIXED .s 1 This is the same as SET FIL TYP BIN .s 1 SET FILE TYPE NOAUTO .s 1 SET FILE NOAUTO disables Kermit-11 from trying to base binary transmission mode on file attributes or filetype. .s 1 SET FILE SUPERCEDE .s 1 SET FILE [NO]SUPERCEDE allows Kermit-11 to accept or reject files received (from either the RECEIVE or GET commands) on a per file basis. The default is SUPERCEDE. By doing SET FILE NOSUPERCEDE Kermit-11 will always check to see if the file to be created is already there (independent of version number) and reject it to the sending server if it exists. This presumes that the Kermit sending the file understands the protocol to reject one file of a (possibly) wildcarded group of files. .br The main use of this is to resume getting a group of files, as in GET KER:K11*.* or GET KER:MS????.* having lost the connection after transferring some of the files. If this is set, then any files already transferred will not be transferred again. .lit Kermit-11>SET FILE SUPERCEDE Kermit-11>SET FILE NOSUPERCEDE .eli .s 1 SET HOME .s 1 SET HOME resets the default device and UIC (or PPN) to nothing, ie, all file opens and creates use your default disk (SY:) and your UIC (or PPN). .lit Kermit-11>SET HOME .eli .s 1 SET IBM-MODE .s 1 The SET IBM ON (or OFF) will instruct Kermit-11 to wait for an XON following each packet sent to an IBM host. Since the default for IBM mode may not always be appropriate for your IBM compatible system, you can always use the SET HANDSHAKE XON and SET DUPLEX HALF to avoid the parity setting implied by using IBM mode. .lit Kermit-11>SET IBM ON Kermit-11>SET IBM OFF .eli .s 1 SET LINE .s 1 The SET LINE command sets the terminal name up for use with the connect command. To use this you must have access to that device. On many systems terminal lines other than your own are protected from access, and may require special procedures to access them. .br The form of the device name is TTnnn:, where 'nnn' is a decimal number for RSTS and an octal number for RSX-11M/M+. For RT-11, the device name is simply the MT unit number shown by the SHO TER command, as in '5' for DZ11 unit 0 line 4. If the system is running RT-11 version 5 you can do a SET LIN XL:. At worst case, Kermit-11 can use the console port on RT-11.

Currently (in 3.54) only the VA4224 has entries for these options. .s 1 SET POS .s 1 The SET POS command allows options SPECIFIC to P/OS to be altered. The most useful option is the SET POS [NO]DTE command. This allows Kermit-11 to use PRO/Communications version 2 for terminal emulation, if this product has been installed on the PRO/350. Of course, if this option is chosen, control is returned to the PRO with the EXIT key (F10) rather than with Control _\C. .lit Kermit-11>SET POS DTE Kermit-11>SET POS NODTE .eli SET PROMPT .s 1 The SET PROMPT command is useful if you are using two Kermit-11's to talk to each other. By using the SET PROMPT command, you can change the prompt from 'Kermit-11>' on either (or both) Kermit to something that would indicate which system you are currently connected to. .lit Kermit-11>SET PROMPT KERMIT-11/1170> Kermit-11>SET PROMPT FUBAR> Kermit-11>SET PROMPT PROKERMIIT-11> .eli .s 1 SET RECEIVE .s 1 Currently the SET RECEIVE and SET SEND basically work the same in that they only alter the END-OF-LINE character and the START-OF-PACKET value, as in: .lit Kermit-11>SET REC START 2 Kermit-11>SET REC END 12 .eli The command SET RECEIVE PACKET-LENGTH command is discussed below. .s 1 SET RECEIVE END-OF-LINE .s 1 This instructs Kermit-11 to expect something other than the default carriage return (octal 15) at the end of a packet. Kermit-11 will ignore packet terminators. The SET SEND END command is of more use in conditioning outgoing packets. .s 1 SET RECEIVE START-OF-PACKET .s 1 The normal Kermit packet prefix is Control-A (1); this command changes the prefix Kermit-11 expects on incoming packets. The only reasons this should ever be changed would be: Some piece of equipment somewhere between the two Kermit programs will not pass through a Control-A; or, some piece of of equipment similarly placed is echoing its input. In the latter case, the recipient of such an echo can change the packet prefix for outbound packets to be different from that of arriving packets so that the echoed packets will be ignored. The opposite Kermit must also be told to change the prefix for its inbound packets and the prefix it uses on outgoing packets. .lit Kermit-11>SET REC START-OF-PACKET 2 .eli .s 1 SET RECEIVE PACKET-LENGTH .s 1 This command has two functions. The first, and normal one, is to reduce incoming packet lengths in the event that normal sized Kermit packets can not be passed through the communications circuit. There could be, perhaps, some 'black box' somewhere in the link that has a very small buffer size; this command could be used to reduce the size that the SENDING Kermit will use. .s 1 The other use is to enable a new protocol extension to Kermit called 'LONG PACKETS'. The actual protocol is documented elsewhere, let's just say that this is a way for two Kermit's to use packet sizes far greater than the normal ('Classic') packet size if 90 characters or so. The main use of this feature is in file transfer over links that introduce considerable delay, it is not uncommon for packets to incur an one to two second delay. The net result is a VERY slow running Kermit with an effective speed of perhaps 300 to 600 baud rather than 1200 or 2400 baud. By making the packets longer, we raise the effective speed of such a circuit. The main restriction on the packet size chosen is the link, a given circuit may not pass 500 character packets. Also, BOTH Kermits must support this extension to the protocol, they will always negotiate it before any file transfer. See the notes at the end of this document for more information. .lit Kermit-11>SET REC PAC 50 Kermit-11>SET REC PAC 600 .eli It is HIGHLY recommended that you use the CRC block check, as the default type one checksum could be inadequate for such long packets, as in: .lit Kermit-11>SET BLO 3 .eli .s 1 SET RECORD-FORMAT .s 1 Kermit wiK11USRRNO[.050032]K11USR.RNO[.050032]    X14|H [4;Ik(&'( k ߫H&P` \RrPP2PPzPP{PPPPP2P~\$\\TD 0D \~ hi) +\ ^( n ^( np\^txY\^ˀ\!kVk<\F˰<˴ˬ\VVkˤ1`@lP ABCDEFGHIJKLMNOPQRSTUVWXYZ$.?0123456789<@<SЬTЬ UQS>?\\\\\\\\\`:#@'="\abcdefghi\\\\\\\jklmnopqr\\\\\\\~stuvwxyz\\\\\\\\\\\\\\\\\\\\\\{ABCDEFGHI\\\\\\}JKLMNOPQR\\\\\\\\STUVWXYZ\\\\\\0123456789\\\\\  !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`ABCDEFGHIJKLMNOPQRSTUVWXYZ{|}~@ggh<i|o<m<4p<p<k|Zn<l fr rwx<x<x<x޺<w@]@@fjnr]Ze@@|> | |v<H|  |  |xz|  |zt f r   < &^ @&@'*/V,"?Lh:hmBmz|z{x`y~|fN|@@|@͂|@ ݃ƃ<ns<|Ŏ |️|ep|u|-@率|<ﾲ2ֻr||ZRM | ntB|xyvZw|J=|R>|J? nnaa|bddfontains a valid RT-11 file structure before trying to read the directory.

The SET RT-11 NOVOL command will instruct Kermit-11 to bypass that check. .lit Kermit-11>SET RT-11 VOL Kermit-11>SET RT-11 NOVOL .eli .s 1 SET SEND .s 1 The SET SEND command controls what Kermit-11 will be doing for outgoing packets in that you may want to alter the packet terminator and/or the start of packet character (by default, 15 octal and 1 octal respectively. See HELP SET RECEIVE for more information. .s 1 The only extra option for SET SEND is SET SEND [NO]XON. If the command SET SEND XON is give, then every packet sent will be prefixed with an XON character. This could be useful in situations where flow control is erratic. The actual intent of this option was to try to circumvent a firmware bug in the DHV11 when used under RSTS/E. .s 1 SET SPEED .s 1 SET SPEED value sets the line speed for the device specified via the SET LINE command, and used for the CONNECT command. Changing the speed of a terminal line requires privilege for RSTS and RSX-11M/M+. The SET SPEED command will only function with a DH11, DHV11, DZ11 or DZV11 multiline interface. .lit Kermit-11>SET SPEED 1200 .eli 1200 Baud would be a normal speed to use with a VA212PA or a DF03. .s 1 Please note that Kermit-11 CAN NOT change the speed of a DL11 type interface, nor can it change the speed of a PDT-150 modem port. For a PDT-150 modem port, use a command of /M/S:nnnn. to change the speed to nnnn for the SPEED.SAV program. .s 1 SET TIMEOUT .s 1 The timeout value tells Kermit how long to wait to get a packet from the other Kermit. If system loads are high, it may be desirable to increase this beyond the default of 10 seconds. .s 1 SET TERMINAL .s 1 The SET TERMINAL command simply controls the way which Kermit-11 prints packet counts while send or receiving a file (or group of files). The simplest way is the default, SET TER TTY. Using SET TER VT100 will cause Kermit to display headers for the numbers printed, at a possible cost in packet speed due to screen control overhead. On the PRO/350, VT100 is assumed. On RSTS/E v9.0 and later, the executive is queried for the terminal type. .lit Kermit-11>SET TER TTY Kermit-11>SET TER VT100 .eli .s 1 SET UPDATE .s 1 The SET UPDATE command controls the frequency at which the packet count display is updated. The default is 1, displaying each packet. A SET UPD 0 will disable all packet count logs, whereas a SET UPD N will update the display every N packets. The SET NOUPDATE command is the same as SET UPDATE 0. .s 2 .subtitle The DIAL command .index The DIAL Command The DIAL command .s 2 The DIAL command is new for version 3.29 of Kermit-11. The DIAL command is used to dial a number on an attached modem of known type (see SET MODEM). To find out the current known modems, use the SET MODEM ? command.

It has additionally been run under Micro-11's and the PRO/350 using the XL and XC handlers respectively. .s 1 #Kermit-11 requires _.TWAIT support as well as multiple terminal support (unless the XL/XC handler is used). The use of multiple terminal support allows Kermit-11 to use any type of interface sysgened, including the DZ11 and DZV11. It is possible under version 5 of RT-11 to use the XL: handler instead of the multiple terminal support. The use of the XL: driver will result in much faster file transfer at high baud rates. Note that XL: must be set up at system startup or at some time later to set the proper speed, CSR and vector. .s 1 For those users who do not have multiple terminal support and do not have the XL handler, Kermit-11 will force the use of the console for data transfers. This will require that Kermit-11 request eight bit prefixing from any other Kermit wishing to send binary data files. Additionally, you can force console mode by doing a SET LINE TT: .s 1 Please note that the device name syntax for terminal lines follows the MT unit numbers, thus if a SHO TER gave unit 5 for DZ11 line 0 the the device name would be: .lit Kermit-11>SET LINE 5 .eli If you use the XL handler, you would do this: .lit Kermit-11>SET LINE XL: .eli To force the console to be used, you would: .lit Kermit-11>SET LINE TT: .eli Additionally, Kermit-11 for RT-11 looks for its help file, K11HLP.HLP, on DK: first and then on SY: if the first one fails. .s 1 #Full wildcarding is supported for RT-11, in the form *.type, name.*, *.* and the % character to match any single character. .s 1 #Kermit-11 can only be built on RT-11 version 5.0 or later due to the use of new assembler directives. .s 1 #Please note that for the connect command under RT-11 and the use of the MT service, you will most likely need xon/off flow control to be generated by Kermit-11. This is enabled with the SET RTFLOW ON command. This is by default OFF since the modem the author uses, a Vadic 212P, can't handle XONs and XOFFs while in command mode. The solution here is to escape back to Kermit command mode after the remote system has been logged into, and then type SET RTFLOW ON. .s 1 #Due to overlaying constraints, the RT-11 Kermit-11 will not accept wildcards for the RENAME and DELETE commands and the REMOTE server equivalents. .s 1 #The executable files are K11XM.SAV for the XM system and PRO/350, and K11RT4 for the FB system. .s 1 #As a final (I hope) RT-11 note, see the RT-11 v5.1 Release Notes page 9-2 and chapter 12.

If they are NOT 176500 and 300, then to use the XL: handler you will need, prior to running Kermit-11, to set them. Suppose the DL vector is 400 and the CSR is 176510.

Also, 2 is swapped for 3. .eli Then, the Kermit-11 command SET DTR, which forces RSTS to raise DTR for 30 seconds, will cause the DTR signal to loop back to the RCD (DCD) signal and thus tell RSTS that there is carrier detect which will raise DTR (the chicken or egg question) and get things rolling. The Kermit-11 HANGUP (or DISCONNECT) command will drop DTR and force the modem to break the connection. .s 2 .index Modems and RSX RSX and Modems .s 1 While the authors experience on RSX is limited, the following notes may be of use. .br Dialing out on a LOCAL line will often require that the modem assert internally DTR. .br If a line is set REMOTE on RSX, the driver will assert DTR and RTS. For a modem, like a VA212PAR strapped at the factory defaults, this will cause the modem to assert DSR and RCD. On the VADIC in particular, the modem will drop RCD during a DIAL command unless the modem is configured to assert RCD continuously. For dialing out, ideally the modem should be able to assert RCD via an option or internally settable strap or switch. If this is not possible, an alternative is to break line 8 (RCD) and jumper DTR (20) to RCD (8) on the CPU side. This will force RSX to always see carrier detect and allow a dial sequence to complete. The Kermit-11 command DISCONNECT (or HANGUP) will still disconnect the modem as the modem will drop from the line when it sees DTR go low (assuming the modem is not strapped to assert DTR internally). .s 1 .subtitle Typical Kermit-11 transfer rates .page .index Typical Kermit-11 transfer rates .s 2 Some sample timings for Kermit-11 and long packet support. The packet size in the RSTS/E to P/OS was 500 bytes, the size from RSTS/E to RSTS/E was 700 bytes. These sizes are somewhat arbitrary, they depend more on the system's buffering capabilities than anything else. .lit Host buffering capabilities: P/OS 500 (estimated) RSTS/E 9.0 or later up to 7000, given sufficient system pool RSX-11M+ 255 (I/D space CPU only) RSX-11M 34 RT-11 134 (could be larger with mod to XC/XL) .eli As it can be seen, large packets make sense only for RSTS/E, P/OS and RSX-11M+ if one wishes to avoid XON/XOFF overhead at high speeds. It should be possible to run larger packets on M+ and RT-11 at lower speeds. .s 1 File transferred: K11POS.TSK, size 102,400 bytes (200 disk blocks) Actual data packet characters AFTER prefixing was 120,857 .lit Time Speed Data rate Comments seconds baud 1436 1200 84/sec 11/44 to PRO/350, 'Classic' Kermit local phone call 1237 1200 97/sec 11/44 to PRO/350, 500 Char packets local phone call 2915 1200 41/sen 11/44 to PRO/350, 'Classic' Kermit local call, 1 second ACK delay. 1492 1200 81/sec 11/44 to PRO/350, 500 Char packets local call, 1 second ACK delay. 304 9600 397/sec 11/44 to 11/44, 'Classic' Kermit, connected locally via Gandalf switch. 245 9600 493/sec 11/44 to 11/44, 700 char packets, connected locally via Gandalf switch. .eli The last two timings are much lower than the line speed due to the fact the the PDP 11/44 is running 100% busy trying to keep up with character interrupts using a normal terminal driver. A special purpose driver, such as the XK driver found on P/OS, would have lower overhead and allow somewhat faster data rates. .s 1 Long packets were chosen for Kermit-11 due to the lack of suitable interrupt driven i/o (at this time) under one of the operating systems, RSTS/E. The Sliding Windows would likely function better in those situations where the circuit delay is much higher, or when the circuit can not accommodate large packet sizes. .subtitle Common problems .index Common problems .s 3 .testK11USRRNO[.050032]K11USR.RNO[.050032]    X14|H [4;Ik(&'( k ߫H&P` \RrPP2PPzPP{PPPPP2P~\$\\TD 0D \~ hi) +\ ^( n ^( np\^txY\^ˀ\!kVk<\F˰<˴ˬ\VVkˤ1`@lP ABCDEFGHIJKLMNOPQRSTUVWXYZ$.?0123456789<@<SЬTЬ UQS>?\\\\\\\\\`:#@'="\abcdefghi\\\\\\\jklmnopqr\\\\\\\~stuvwxyz\\\\\\\\\\\\\\\\\\\\\\{ABCDEFGHI\\\\\\}JKLMNOPQR\\\\\\\\STUVWXYZ\\\\\\0123456789\\\\\  !"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`ABCDEFGHIJKLMNOPQRSTUVWXYZ{|}~@ggh<i|o<m<4p<p<k|Zn<l fr rwx<x<x<x޺<w@]@@fjnr]Ze@@|> | |v<H|  |  |xz|  |zt f r   < &^ @&@'*/V,"?Lh:hmBmz|z{x`y~|fN|@@|@͂|@ ݃ƃ<ns<|Ŏ |️|ep|u|-@率|<ﾲ2ֻr||ZRM | ntB|xyvZw|J=|R>|J? nnaa|bddf page 4 .c;Common problems in file transfer .s 2 Connection fails. .s 1 Check modem control signals. RSX needs TC.DLU set to two to talk to a dial out modem, otherwise you will need to strap or jumper signals in the modem to have carrier detect set high. RSTS/E also should have the modem assert carrier detect. If not, see the previous notes about modems. If all else fails, put a breakout box in the line and observe what signals are present. .s 1 File transfer fails. .s 1 If the file transfer aborts on retries immediately, there may be a parity problem. If the problem shows up on binary files, try a SET PAR SPACE command to Kermit; that will force eight bit data to be prefixed into seven bits. If you instead get a retry about once every 10 seconds, the other Kermit is not responding and your Kermit is timing out. Check to see if your connection is still present, and try the SET PARITY command. .br If you are sending binary data between unlike Kermits, you will most likely have to give the proper command to each to prepare them for the binary data; this is the SET FILE command; for Kermit-11 it's SET FIL BIN (or SET FIL TYP FIX); for VMS Kermit it's SET FIL TYP FIX. .br If your Kermit's packets are being echoed back, try a SET SEND START value command for your Kermit, and a SET REC START same_value for the other Kermit.
