- ; This is the CP/M-80 implementation of the Columbia University
- ; KERMIT file transfer protocol.
- ;
- ; Version 4.0

- ; Originally written by Bill Catchings of the Columbia University Center for
- ; Computing Activities, 612 W. 115th St., New York, NY 10025.

- ;
- ; This is the header for the system-independent portion of KERMIT, which
- ; consists of the following files (in this order):
- ;
- ; CPSKER.ASM - this file
- ; CPSDEF.ASM - definitions for both KERMIT and KERSYS
- ; CPSMIT.ASM - \initialization, main loop, miscellaneous commands
- ; CPSCOM.ASM - /(BYE, EXIT, LOG, SET, SHOW, and STATUS) (Part1 of 2)
- ; CPSPK1.ASM - \the KERMIT protocol handler (SEND, RECEIVE, LOGOUT,
- ; CPSPK2.ASM - / and FINISH commands) (In two parts)
- ; CPSREM.ASM - REMOTE commands etc
- ; CPSSER.ASM - SERVER commands etc (Empty as yet)
- ; CPSTT.ASM - the transparent commands (TRANSMIT, CONNECT)
- ; CPSCPM.ASM - CP/M commands (DIR, ERA)
- ; CPSWLD.ASM - the wildcard handler
- ; CPSCMD.ASM - the command parser
- ; CPSUTL.ASM - utility routines
- ; CPSDAT.ASM - Data space and the overlay link space
- ;
- ; When building the system-independent part with M80 or MAC80, CPSKER
- ; INCLUDEs the other files; when building with LASM, each file LINKs to
- ; the next file.
- ;
- ; For now, the system-dependent routines are all in CPSSYS.ASM, with
- ; the actual configuration defined in CPSTYP.ASM.
- ;
- ; revision history (latest first):
- ;
- ; Begin CP/M Kermit-80 version 4.11.
- ;edit 32, 1-Apr-1991 by MF. Official release of work to date as CP/M Kermit
- ; (Kermit-80) Version 4.11.
- ; Modified edit level of cpscpm.asm to reflect a bug fix for the TYPE
- ; command introduced with edit 13.
- ;edit 31, 29-Mar-1991 by MF. Modified edit levels of cpsker.asm,
- ; cpscom.asm and cpsdat.asm to reflect rename of parameter vermin to
- ; revno (revision level) and change of SET COLLISION REPLACE to
- ; SET COLLISION OVERWRITE to conform with C-Kermit. Modified
- ; edit level of cpsrem.asm to reflect change from REMOTE SET FILE
- ; COLLISION REPLACE to REMOTE SET FILE COLLISION OVERWRITE.
- ; Modified edit level of cpsutl.asm to reflect code tightening and
- ; edit levels of cpsmit.asm and cpspk2.asm to close any open TAKE-file
- ; and abort take-file processing if ^C is typed from the console
- ; Also corrected ^Z test in cpsmit.asm in INPUT command ("inp2b")
- ; Implement "file not found" complaint if a TAKE command can't find
- ; the TAKE-file and it's not the initial TAKE (KERMIT.INI)
- ; Modified edit level of cpscpm.asm to reflect modification of the
- ; TYPE and PRINT commands to cancel file typeout/printout completely
- ; if ^C is entered on the console (either immediately or after a key
- ; has been pressed to induce a pause) and to immediately begin
- ; typeout/printout of the next file (if the filespec was wild-carded)
- ; if ^X is entered (either immediately or after a key has been pressed
- ; to induce a pause).
- ; Modified edit levels of cpsmit.asm and cpscom.asm to reflect addition
- ; of the STAY command as a synonym for SET NO-EXIT.
- ;edit 30, 27-Feb-1991 by MF. Modified edit levels of cpscom.asm,
- ; cpsmit.asm, cpsutl.asm and cpsdat.asm to reflect provision for
- ; a "revision level" field (1-26=A-Z), addition of QUIT as a synonym
- ; for the EXIT command, recognition of C, R and S as abbreviations
- ; for the CONNECT, RECEIVE and SEND commands, respectively, display
- ; of Kermit version in the VERSION command and a fix to the TAKE-file
- ; input routine "r1tchr" to prevent semicolons from being interpreted
- ; as command separators during TAKE-file execution. This last fix
- ; allows such commands as REMOTE DELETE *.*;* to Kermit-32 to
- ; operate as expected.
- ;edit 29, 14-Feb-1991 by MF. Updated edit levels of cpscom.asm,
- ; cpscpm.asm, cpsdat.asm and cpsrem.asm to reflect bug fixes,
- ; code tightening and simplified routine "remcli" (in cpsrem.asm)
- ; which gets text to be passed on to a remote Kermit in REMOTE
- ; Kermit commands.
- ;edit 28, 8-Feb-1991 by MF. Changed edit level of cpscpm.asm to reflect
- ; a bug fix to make TAKE-files work properly with commands such as
- ; INPUT which check the keyboard for input.
- ;edit 27, 30-Jan-1991 by MF. Changed edit levels of cpscpm.asm, cpsrem.asm,
- ; cpstt.asm and cpsutl.asm to reflect bug fixes and enhancements
- ;edit 26, 17-Jan-1991 by MF. Changed edit level of cpscmd.asm to
- ; reflect fixes to allow leading spaces/tabs to be ignored when
- ; parsing keywords (this was the intent but the code never worked
- ; correctly) and to blank the entire fcb in "cmifil" to allow successive
- ; COPY commands to function properly. Also changed edit level of
- ; cpspk1.asm to reflect further work on "disk full" error reporting.
- ;edit 25, 14-Jan-1991 by MF. Incremented edit level of cpspk1.asm to
- ; reflect bug fix to "disk full" error reporting code so <cr><lf>
- ; is not sent directly to the Remote Kermit. This per a report from
- ; Russell Lang of Australia's Monash University.
- ;edit 24, 10-Jan-1991 by MF. Modified edit level of cpxtyp.asm to
- ; reflect addition of "terminal required" message for some.
- ; machines.
- ;edit 23, 7-Jan-1991 by MF. Modified edit levels of cpxtyp.asm, cpxswt.asm,

- ; phoned-in bug-report to Dr. Martin J. Carter of Nottingham
- ; University in the U.K. (PPZMAJOC@vax.ccc.nottingham.ac.uk)
- ;edit 19, 14-Dec-1990 by MF. Modified edit level of cpspk2.asm to reflect
- ; modification to "gofil" to allow drive specifications in 2nd
- ; filename of GET and RECEIVE commands; also modified edit levels of
- ; cpspk1.asm and cpsrem.asm to reflect addition of "<<>>" around
- ; "X" or "F" packets coming as a reply to a REMOTE command and
- ; deletion of an unnecessary instruction before label remc2d
- ; in cpsrem.asm.
- ;edit 18, 9-Dec-1990 by MF. Modified edit levels for Version 4.10
- ; yet another time to reflect changes in CPSDAT.ASM to clarify
- ; "File size on DIR" status message.
- ;edit 17, 4-Dec-1990 by MF. Adjusted edit levels of cpscom.asm/cpsdat.asm

- ;edit 8, 30-Oct-1990 by Michael Freeman; 301 N.E. 107th Street;
- ; Vancouver, WA 98685 USA; Telephone (206)574-8221.
- ; Work: Bonneville Power Administration
- ; P.O. Box 491 M/S MORF
- ; Vancouver, WA USA 98666
- ; Telephone (206)690-2307
- ; Implemented FRENAME command to rename a CP/M file.
- ; Implemented many Remote commands, variable-length packets up thru
- ; 94 characters in length. Fixed a bug in CPSCOM.ASM in the
- ; routine "getnp" and a bug in CPSCOM.ASM which caused garbage to appear
- ; on the screen when PRTSTR was called with QUIETD flag set.
- ; Modified code in module CPSCMD.ASM to skip leading spaces and tabs
- ; when getting Kermit commands from the CP/M command line. This also
- ; obviates the necessity to type a leading semicolon to separate the
- ; Kermit command from the Kermit commands on the CP/M command line.
- ; Fixed code in CPSPK2.ASM which handles file collision detection
- ; and resulting file rename per my entries in CPKERM.BWR.
- ; and included fix by Russell Lang of Dept. of Electrical and Computer
- ; Engineering, Monash University, Australia, to prevent renamed
- ; files with SET WARNING ON from having the attributes (e.g., R/O)
- ; copied from original file. Mr. Lang's E-mail address is:
- ; Russell Lang Email: rjl@monu1.cc.monash.edu.au Phone: (03) 565 3460
- ; Department of Electrical and Computer Systems Engineering
- ; Monash University, Australia
- ; Also fixed a bug in CPSPK2.ASM which prevented completion messages
- ; from being displayed if terminal was set to QUIET.
- ; Implemented most proposed SET FILE-COLLISION (COLLISION) commands.
- ; Implemented SET INCOMPLETE file disposition command.
- ; Implemented a few of the proposed REMOTE SET commands.
- ; Implemented other fixes suggested in CPKERM.BWR.
- ; Moved overlay address to 6C00H.
- ; Changed location of .printx in this file so LASM doesn't complain.
- ; In system-dependent modules, included HP-125 support.
- ; Also modified Telcon Zorba code in CPXHEA.ASM to enable setting
- ; of baud-rates and sending of a break.
- ; Included Russell Lang of Monash Univ. Australia's implementation
- ; for the Microbee series of computers (CPXBEE.ASM).
- ; Fixed COMPUPRO version of Kermit to compile correctly and to
- ; conform to current syntax for setting baud-rate.
- ; edit 7, September, 1987. Added files for SERVER and REMOTE
- ; modules (CPSSER/CPSREM). SERVER is still empty, and may be
- ; only wishfull thinking. I have ideas, but I dont think I
- ; will have the time to implement it.
- ;
- ; edit 6: 30 March, 1987 by OBSchou. Start Kermit-80 V4.09 with the
- ; overlay address at 6000h. Also adjusted the INCLUDEs to allow
- ; M80 to assmeble these files.
- ;
- ; edit 5: 20 June, 1986. Have added so much code etc that the overlay had to
- ; be moved again.. give it to 5000h. This starts off Kermit-80 V4.08
- ;
- ; edit 4 22 April 1986
- ; Start work on 4.06. This should clear up a couple of bugs, add in
- ; a few features, and split the system dependent stuff into
- ; smaller units.
- ;
- ; edit 3a 7 March 86 OBSchou Loughborough england. Minor additions
- ; to cpsker.asm, cpscmd.asm and cpspkt.asm.
- ;
- ; edit 3: February 10, 1985 (CJC)
- ; Update for v4.05; add "verno" so CPSUTL doesn't have to change
- ; just because some other module did.
- ;
- ; edit 2: September 10, 1984 (CJC)
- ; Update for v4.03.
- ;
- ; edit 1: July 27, 1984 (CJC)
- ; Created to allow assembly of Kermit by LASM as well as MAC80 and M80.
-
- verno EQU 11 ; minor version number
- revno EQU 0 ;[MF]Revision level
- ;[MF]0-26 yields A-Z
-
- ; Version 4.10 of Kermit consists of the following edit levels:
- ; cpsker.asm edit 32
- ; cpsdef.asm edit 9
- ; cpsmit.asm edit 30
- ; cpscom.asm edit 13
- ; cpspk1.asm edit 23
- ; cpspk2.asm edit 11
- ; cpsrem.asm edit 13
- ; cpsser.asm edit 1
- ; cpstt.asm edit 12
- ; cpscpm.asm edit 14
- ; cpswld.asm edit 4
- ; cpscmd.asm edit 13
- ; cpsutl.asm edit 30
- ; cpsdat.asm edit 19
- ; cpxlnk.asm edit 8 (cpslnk.asm is not assembled with cpsker, but it
- ; defines the linkage area expected by cpsker, and so must
- ; match the description in cpsutl.asm)
- ; cpxswt.asm edit 10
- ;
- ; Version 4.10 of Kermit has been tested with the following edit levels of
- ; the system-dependent files:
- ; cpxtyp.asm edit 34
- ; cpxsys.asm edit 40
- ; cpxhea.asm edit 4
- ; cpxtor.asm edit 4
- ; cpxbbi.asm edit 4 (Ampro Little Board)
- ;
- ; Version 4.10 of Kermit is still to be tested fully against all known systems
- ; so far included in the system dependent overlays.
- ;
-
-
- FALSE equ 0
- TRUE equ NOT FALSE
-
- cpsker equ TRUE ; building system-independent part
- debug equ FALSE ; set false for running system. True => does some
- ; unusual or unexpected things.
- ;
- ; Assembler type. Define the appropriate one TRUE, the rest FALSE. (We can't
- ; use ASM, because it cannot handle multiple input files)
- mac80 EQU FALSE ; For assembly via MAC80 cross-assembler.
- m80 EQU false ; For assembly via Microsoft's M80.
- lasm EQU true ; For assembly via LASM, a public-domain
- ; assembler.
- ;
- ; Get the other modules...
-
- IF lasm ; If we're linking, go on to the next file.
- LINK CPSDEF
- ENDIF;lasm
-
- ; If we're still here, we must be using M80 or MAC80. M80 doesn't
- ; like ENDs inside conditionals, but the END statement has to be
- ; in CPSUTL for LASM (otherwise, we'd need a file containing just an
- ; END statement). So, we leave off the IF m80 OR mac80 conditional
- ; that ought to be around these INCLUDEs. No problem until the next
- ; incompatible assembler comes along...
- ; Let's first say where we are:
- ;
- .printx * CPSKER.ASM (or nearest offer) *
- ;
- .printx * CPSDEF.ASM *
- INCLUDE CPSDEF.ASM ; definitions
- .printx * CPSMIT.ASM *
- INCLUDE CPSMIT.ASM ; initialization, main loop, some commands
