/ DOCUMENT AND THE PROGRAM(S) DESCRIBED IN IT, EXCEPT FOR EXPLICITLY COMMERCIAL
/ PURPOSES.
/ EDIT HISTORY. /014 CJL
/ 052 06-SEP-1990 BUG FIX. CHARLES LASNER (CJL)
/ SENDING A FILE WHICH EXACTLY FILLS THE LAST DATA PACKET AT THE
/ END OF THE FILE WILL CAUSE THE PACKET TO BE SENT TWICE. THE
/ ROUTINE DIDN'T CHECK FOR AN EMPTY OUTPUT BUFFER AT EOF.
/ 051 29-AUG-1990 BUG FIX. CJL
/ PDP-8/A NOT IDENTIFIED CORRECTLY IN CPUID ROUTINE. THE UPDATED
/ PC IS WHAT IS LOADED INTO THE AC WHEN 7016 IS EXECUTED ON THE
/ KK-8/A CPU. THE ROUTINE WAS CHECKING FOR THE NON-UPDATED VALUE.
/ ALSO NEW DOCUMENTATION FOR PRE-CLEARING MEMORY FOR BENEFIT OF
/ ENCODED BINARY FILES.
/ 050 06-SEP-1989 DECMATE I SUPPORT, ETC. CJL
/ THIS EDIT IMPLEMENTS DECMATE I SUPPORT USING THE DP278-A OR -B.
/ A NEW CONDITIONAL 'PORT' SELECTS WHICH PORT IS TO BE USED. IF
/ KERMIT-12 IS RUN ON DECMATE I (WHILE NOT CONFIGURED FOR SERIAL
/ PRINTER PORT COMMUNICATIONS; SEE EDIT 048.) THEN REMOTE
/ COMMUNICATIONS TAKES PLACE ON THE PORT SELECTED AT ASSEMBLY TIME
/ ('PORT=0' OR 'PORT=1'). ADDED BAUD RATE PARAMETER 'BRATE' TO
/ SELECT REMOTE COMMUNICATIONS BAUD RATE FROM THE STANDARD TABLE;
/ DEFAULTS TO 1200 BAUD ('BRATE=7').
/ 049 30-AUG-1989 REMOTE FLOW CONTROL, ETC. CJL
/ THIS EDIT IMPLEMENTS FLOW CONTROL SUPPORT (IF FLOW CONTROL IS
/ ENABLED) FOR THE REMOTE LINE WHILE SENDING PACKETS TO THE REMOTE
/ KERMIT REGARDLESS OF STATE. PREVIOUSLY, FLOW CONTROL ONLY
/ APPLIED TO CONNECT MODE. LOCAL FLOW CONTROL (TOWARDS THE REMOTE
/ KERMIT) IS UNNECESSARY AS LOCAL BUFFERS FOR REMOTE INPUT ARE
/ ALWAYS AVAILABLE. CERTAIN ROUTINE CHANGES MADE FOR BENEFIT OF
/ DECMATE I SUPPORT IN A SUBSEQUENT EDIT.
/ 048 24-AUG-1989 DECMATE II, ETC. SUPPORT. CJL
/ ONCE-ONLY CODE ADDED TO IMPLEMENT DECMATE II, ETC. REMOTE LINE
/ SUPPORT ON SERIAL COMMUNICATIONS PORT. SELECTED PORT IS
/ INDICATED ON OPENING BANNER IF OPERATING ON DECMATE.
/ THIS EDIT PROVIDES BASIC SUPPORT OF THE DECMATE II COMMUNICATIONS PORT AS AN
/ AUTOMATIC FEATURE OF THE STANDARD RELEASE OF K12MIT. AUTOMATIC DETECTION OF
/ DECMATE II, ETC. HARDWARE IS PERFORMED UNLESS THE PDP-8-TYPE REMOTE LINE
/ SUPPORT IS ASSEMBLED FOR THE SERIAL PRINTER AS THE REMOTE LINE ('SPRINT' IS
/ SET OR EQUIVALENT).
/ THIS EDIT INCORPORATES ALL OF THE INFORMATION TAKEN FROM VARIOUS SOURCES
/ REGARDING DECMATE PORT INITIALIZATION, ETC. EVERY ATTEMPT HAS BEEN MADE TO
/ COMPLETELY SET ALL APPROPRIATE REGISTERS, ETC. FOR DECMATE II, III, III+
/ OPERATION. NO SUPPORT EXISTS FOR THE DECMATE III BUILT-IN MODEM OPTION, AS
/ EXPLICIT DOCUMENTATION IS NOT AVAILABLE (SOME OF THE INITIALIZATION CODE IS
/ APPARENTLY USED TO DISABLE THE MODEM). THESE ROUTINES ARE ONLY KNOWN TO WORK
/ ON THE DECMATE II, AS THE III (ESPECIALLY WITH OPTIONAL MODEM) AND THE III+
/ HAVEN'T BEEN AVAILABLE TO THE AUTHOR FOR TESTING. THE INITIALIZATION CODE
/ WILL BE UPDATED LATER TO INCLUDE PANEL REQUESTS, ETC. TO CORRECT ANY
/ PROBLEMS, ETC. DECMATE-SPECIFIC FEATURES (SUCH AS SETUP COMMANDS) WILL BE
/ ADDED LATER AND ENABLED FROM THESE ROUTINES.
/ THIS EDIT INCORPORATES NON-INTERRUPT ROUTINES WHICH HAVE BEEN TESTED AT THE
/ MAXIMUM COMMUNICATIONS SPEED OF THE DECMATE II (19200 BAUD). THEY WILL
/ SUFFICE FOR ALL KERMIT IMPROVEMENTS SHORT OF SLIDING WINDOWS AT WHICH TIME
/ INTERRUPT-DRIVEN I/O WILL BE REQUIRED. (INTERRUPT-DRIVEN I/O IS ILLEGAL ON
/ CERTAIN OS/8 SYSTEMS WHERE INTERRUPTS ARE HARMFUL TO THE SYSTEM OR NON-SYSTEM
/ HANDLERS.)
/ 047 21-AUG-1989 CODE CLEANUP. CJL
/ STREAM-LINED CONNECT MODE ROUTINES FOR MINIMUM USE OF IOTS. THIS
/ IS IN PREPARATION FOR EVENTUAL DECMATE II OPERATION, AND TO
/ MINIMIZE K12PCH PATCH FILE SIZE. CERTAIN NON-CONNECT ROUTINES
/ MOVED TO FACILIATE CONNECT ROUTINE REORGANIZATION.
/ 046 15-AUG-1989 CODE CLEANUP. CJL
/ ADDED NEW (NON-CONNECT) MODE COMMUNICATIONS ROUTINES FOR EVENTUAL
/ DECMATE USE. ELIMINATION OF 'IREM' AND 'IREMW' ROUTINES IN FAVOR
/ OF 'COMIN'. ELIMINATION OF 'OREM' IN FAVOR OF 'COMOUT'. ADDED
/ STATUS UPDATE ROUTINE ('UPSTATUS') FOR EVENTUAL DECMATE II, ETC.
/ USAGE. ELIMINATED PDP-8, DECMATE I, DECMATE II CONDITIONALS.
/ REORGANIZED SERIAL LINE CONDITIONALS AND ADDED NEW 'SPRINT'
/ PARAMETER FOR SERIAL PRINTER PORT USAGE AS COMMUNICATIONS PORT.
/ ADDED ONCE-ONLY CODE ADDED TO AUTOMATICALLY RECOGNIZE DECMATE I
/ AND II OPERATION UNLESS ASSEMBLED FOR REMOTE COMMUNICATIONS ON
/ SERIAL PRINTER PORT ('SPRINT' SET). UPDATED K12PCH.PAL TO
/ CORRESPOND TO NEW DEFINITIONS. DEFINED EVENTUALLY NEEDED
/ COMMUNICATIONS PORT INSTRUCTIONS FOR DECMATE II; ACTUAL DECMATE
/ II OPERATION WILL BE DEFINED IN A SUBSEQUENT EDIT. DOCUMENTED
/ NEW LOADING AND SAVING INSTRUCTIONS FOR K12MIT TO ALLOW FOR
/ ONCE-ONLY CODE IN 10000-11777 WITHOUT SWAPPING THE CODE OUT FOR
/ THE USR. THIS ELIMINATES OVERHEAD WHEN LOADING K12MIT, BUT IS
/ DIFFERENT FROM THE FORMER INSTRUCTIONS WHICH ASSUMED NO OTHER
/ USAGE OF 10000-11777 OTHER THAN THE (LOCKED-IN) USR.
/ THIS EDIT PROVIDES THE FRAMEWORK FOR AUTOMATIC DETECTION OF PROGRAM EXECUTION
/ OF K12MIT ON ANY MEMBER OF THE DECMATE FAMILY (I, II, III, III+). WHEN
/ 6120-TYPE CPU DETECTION OCCURS, THE DECMATE I OR II-TYPE COMMUNICATIONS PORT
/ INITIALIZE CODE IS AUTOMATICALLY SELECTED AS NECESSARY UNLESS THE PDP-8-TYPE
/ ROUTINES ARE ASSEMBLED (WITH 'SPRINT' SET OR EQUIVALENT USER SETTINGS, ETC.)
/ FOR THE VT-78-TYPE PRINTER PORT (32/33), IN WHICH CASE THE COMMUNICATIONS IS
/ DONE VIA THE PRINTER PORT ON THE DECMATE (WHICH IS ALMOST PDP-8 COMPATIBLE AND
/ IS ACCOMODATED AS SUCH).
/ SUBSEQUENT EDITS SHOULD PROVIDE FOR A DECMATE I PARAMETER TO CONTROL THE PORT
/ SELECTION, AS THERE ARE AT LEAST TWO VARIANT OPTIONS BOARDS (DP-278A AND
/ DP-278B) EACH CONSISTING OF TWO PORTS.
/ 045 12-AUG-1989 BUG FIX. CJL
/ FINISH, GET, AND RECEIVE COMMANDS FAIL TO ABORT PROPERLY
/ (ESPECIALLY AFTER THE SEND COMMAND HAS BEEN USED), AS THE CURRENT
/ OPERATING MODE ('KMODE') IS NEVER PROPERLY SET, OR IS SET AFTER
/ SEVERAL PACKETS HAVE BEEN SENT. EACH COMMAND NOW SETS ITS OWN
/ OPERATING MODE BEFORE INITIATING ANY PACKETS.
/ 044 11-AUG-1989 CODE CLEANUP. CJL
/ CHANGED 'CCMSG' TO 'ABMSG' WITH CLEARER MESSAGE. CHANGED
/ 'CCFLAG' TO 'ABFLAG' FOR CONSISTENCY. CHANGED ABORT CHARACTER
/ FROM <^C> TO CHOICE OF <^X> OR <^Z> FOR CONSISTENCY. ELIMINATED
/ 'ITTY' AND 'ITTYW' ROUTINES BY USING 'CTLCTST' AND 'INPUT'
/ ROUTINES ALREADY AVAILABLE A/O EDIT 043. ELIMINATED 'TCHAR' IN
/ FAVOR OF 'INCHAR' AVAILABLE A/O EDIT 043.
/ 043 07-AUG-1989 CODE CLEANUP, ETC. CJL
/ REWRITE OF CONSOLE SUPPORT ROUTINES INCLUDING FORCED-ECHO OUTPUT
/ AND COLUMN COUNT FOR <HT> SIMULATION IN PREPARATION FOR IMPENDING
/ USER-INTERFACE REWRITE. 'SCRIBE', 'LININP', AND 'ESCPRNT'
/ ROUTINES NOW CALL "P7ECHO" ROUTINE TO ENSURE PRINTING OF CRUCIAL
/ MESSAGES.
/ 042 13-JUN-1989 CODE CLEANUP. CJL
/ FIXED VARIOUS NAK-RELATED BUGS AND SEND-INIT PROBLEMS AS IN K278
/ (SOME OF THE K278 STUFF IS DEFICIENT!). CALCULATION OF PROPER
/ SEQUENCE NUMBER FOR NAK CORRECTED OVER FORMER (K08MIT AND K278)
/ VERSIONS. ADDED ERROR MESSAGE FOR FULL-DISK PROBLEM.
/ 041 12-MAY-1989 BUG FIX. CJL
/ VARIOUS VERSIONS (DECMATE) WON'T FUNCTION REMOTELY WHILE KL-8
/ VERSIONS WORK FINE. ADDED REMOTE LINE READ IOT TO INITIALIZE
/ REMOTE LINE AT STARTUP TIME FOR VERSIONS REQUIRING THIS.
/ CORRESPONDING CHANGES IN PATCH FILE MADE FOR REMOTE LINE READ IOT
/ IN TWO PLACES.
/ 040 07-MAR-1989 COSMETIC CLEANUP. CJL
/ CLEANUP OF EDIT HISTORY AND OTHER COMMENTS.
/ 039 21-MAY-1988 CODE CLEANUP. CJL
/ ADDED VARIABLE 'INIECHO' TO ALLOW DEFAULT CONNECT-MODE STATE TO
/ BE HALF-DUPLEX ("SET LOCAL-ECHO ON"). MODIFIED INPUT SERVICE
/ ERROR ADDRESSES TO SIMPLIFY ERROR TABLES.
/ 038 19-MAY-1988 CODE CLEANUP. CJL
/ ELIMINATED TRAILER FILES DURING ASSEMBLY BY CREATING VARIABLES
/ 'GENMSG' AND 'UMSG.' THIS ALLOWS THE HEADER FILE (PARAM.PA) TO
/ CONTAIN THE LOCAL MESSAGE TEXT WITHOUT SUBSEQUENT OVERLAY (WHICH
/ WAS WHY THERE FORMERLY WAS A TRAILER FILE CAPABILITY). OVERLAY
/ BY K12PCH.BN WILL DEFAULT TO CREATION OF A DUMMY USER MESSAGE
/ (WITHIN K12PCH) ENCOURAGING LOCAL CUSTOMIZATION. K12MIT.BN WILL
/ CONTAIN A NULL MESSAGE BY DEFAULT UNLESS CUSTOMIZED IN PARAM.PA.
/ 037 21-JAN-1988 BUG FIX. CJL
/ RESET OS/8 DEVICE CONTROL WORD TABLE TO DELETE TENTATIVE FILE IN
/ CASE OF PRIOR INPUT SERVICE ERROR.
/ 036 20-JAN-1988 BUG FIX. CJL
/ RESET 'OFFLG' WHEN DOING INPUT SERVICE IN CASE PRIOR ERRORS LEAVE
/ THE FLAG SET.
/ 035 14-JAN-1988 USR RESIDENT CODING. CJL
/ CALLS TO USR NOW USE 10200 INSTEAD OF 17700. NO SWAP OVERHEAD
/ WHEN OPENING OR CLOSING FILES.
/ 034 13-JAN-1988 CODE CLEANUP. CJL
/ ALL EIGHT-BIT ORIENTED CONSOLE CODE ELIMINATED; NOW IGNORES
/ PARITY (JUST SEVEN BITS).
/ 033 12-JAN-1988 CODE CLEANUP. CJL
/ 'TTYOUT' AND 'OTTY' ROUTINES ELIMINATED; NOW USES 'P7CH' FOR ALL
/ CONSOLE OUTPUT (EXCEPT FOR CONNECT MODE).
/ 032 12-JAN-1988 CODE CLEANUP. CJL
/ VARIOUS ROUTINES REWRITTEN TO ELIMINATE DEPENDENCIES ON CPU TYPE
/ BEYOND THE CLASSIC PDP-8.
/ 031 11-JAN-1988 CODE CLEANUP. CJL
/ ELIMINATED 'RTDISP' AND CHANGED CALLING CONVENTION FOR DISPATCH
/ ROUTINE. ALL CALLERS NOW LOCAL OR VIA LOCAL POINTERS. ADDED
/ SEVERAL CONDITIONAL PARAMETERS AND LABELS FOR BENEFIT OF
/ K12PCH.PAL.
/ 030 05-JAN-1988 CODE CLEANUP. CJL
/ CHANGED LOWER/UPPER CASE CONDITIONAL ASSEMBLY PARAMETERS AND MORE
/ EFFICIENT CODE.
/ 029 21-DEC-1987 CODE CLEANUP. CJL
/ CHANGED CALLING CONVENTIONS FOR 'SCRIBE' AND SIMILAR ROUTINES AND
/ REWROTE 'COMMAND' ROUTINE.
/ 028 15-DEC-1987 CODE CLEANUP. CJL
/ COMPLETE REWRITE OF FILE LOOKUP ROUTINE. 'LUKUP' NOW USES FIELD
/ ONE BUFFER AND ITS OWN AUTO-INDEX REGISTER CONSERVING PROGRAM
/ SPACE.
/ 027 05-DEC-1987 CODE CLEANUP. CJL
/ CHANGED DISPATCH ('DISPA0') ROUTINE TO USE 'SRCHTABLE' ROUTINE.
/ ALL CALLS MADE COMPATIBLE. ELIMINATED 'SCANC' CODE. ELIMINATED
/ CODE WITHIN 'DPARS' ROUTINE. 'LUKUP' ROUTINE NOW DOES ITS OWN
/ DISK I/O. ELIMINATED 'BLKIN' ROUTINE.
/ 026 27-NOV-1987 NEW CONNECT MODE CODE. CJL
/ TOTAL REWRITE OF ALL CONNECT MODE CONSOLE AND REMOTE INPUT AND
/ OUTPUT TERMINAL ROUTINES. CONNECT IS NOW FULLY BUFFERED IN ALL
/ DIRECTIONS. IF FLOW CONTROL IS OBEYED, ANY BAUD RATE CAN BE
/ ACCOMODATED BOTH LOCALLY AND REMOTE (UP TO 9600 BAUD TESTED,
/ SHOULD WORK TO AT LEAST 19200 BAUD BY INSPECTION). TESTED WITH
/ FAST VT-100 EMULATOR CONSOLE TO PROVE ESCAPE SEQUENCES ARE NOT
/ DROPPED WHEN LOCAL TERMINAL IS FASTER THAN REMOTE LINE. LIMITED
/ USE OF SUBROUTINES TO IMPROVE HIGH BAUD RATE OPERATION. ADDED
/ TABLE-DRIVEN ERROR EXIT ROUTINE FOR SEND ROUTINES.
/ THIS EDIT PROVIDES FULLY BUFFERED INPUT/OUTPUT ROUTINES FOR BOTH LOCAL AND
/ REMOTE PORTS. NO INTERRUPTS ARE USED FOR MAXIMUM COMPATIBILITY WITH OS/8
/ DEVICES (SOME OF WHICH ARE INTOLERANT OF INTERRUPTS, SUCH AS TD-8/E). REMOTE
/ FLOW CONTROL (IF ENABLED) WILL SIGNAL BUFFER FILLING VIA <DC3> WHEN THE BUFFER
/ IS 3/4 FULL. WHEN THE BUFFER REACHES 1/4 FULL, THE REMOTE WILL BE SENT <DC1>
/ TO ALLOW FURTHER OUTPUT. REMOTE FLOW CONTROL IS SUPPORTED IN BOTH DIRECTIONS;
/ LOCAL FLOW CONTROL IS FROM THE KEYBOARD ONLY.
/ WHILE THE CONSOLE OUTPUT IS PAUSED BY <DC3>, THE BUFFER WILL FILL WITH OUTPUT
/ CHARACTERS. WHEN THE USER RELEASES THE CONSOLE WITH <DC1>, THE BUFFER WILL
/ RAPIDLY EMPTY (ASSUMING THE CONSOLE IS FASTER THAN THE REMOTE LINE). THIS
/ ALLOWS THE USER TO PAUSE THE CONSOLE WITHOUT BACKING UP THE REMOTE LINE UP TO
/ THE LIMITS OF BOTH LOCAL OUTPUT AND REMOTE INPUT BUFFERS.
/ 025 24-NOV-1987 NEW FEATURES AND CODE CLEANUP. CJL
/ PROPER INTERRUPT SETUP FOR <^C> AND <^P>, ECHO STATE. ALL
/ MESSAGES IN NEW FORMAT, (SOME NEW ONES HAVE BETTER CONTENT).
/ ELIMINATED 'PRI6B' AND 'REM6B' ROUTINES. NEW AND IMPROVED INPUT
/ SERVICE ERROR CODE MOVED TO PROPER PAGE. REWROTE CONNECT
/ ROUTINES TO ALLOW NON-INTERRUPT BUFFERED I/O LATER. CREATED NEW
/ VARIABLE 'ESCHAR' AND PARAMETER 'ESCAPE' TO SET DEFAULT ESCAPE
/ CHARACTER. ESCAPE CHARACTER CAN BE CHANGED IN MEMORY AND WILL BE
/ USED CORRECTLY BY ALL ROUTINES. ADDED 'ESCPRNT' ROUTINE TO
/ HANDLE ALL CASES (INCLUDING NON-CONTROL CHARACTERS). DEFAULT
/ ESCAPE PARAMETER VALUE COMPATIBLE WITH K08V2, BUT IS A USER
/ PARAMETER, CONFIGURED AS OTHER PARAMETERS DEFINED IN EDIT 017.
/ CREATED ESCAPE FUNCTION TABLE FOR EXPANSION LATER. NOW SUPPORTS
/ ESCAPE C(LOSE) IN UPPER OR LOWER CASE, ESCAPE ESCAPE (SEND ONE
/ ESCAPE CHARACTER). ALL BAD ESCAPE COMMANDS WILL ISSUE <BEL>
/ CHARACTER TO WARN USER THAT COMMAND IS ILLEGAL AND OTHERWISE WAS
/ IGNORED. CREATED NEW VARIABLE 'ECHOFLAG' TO ALLOW LOCAL ECHO IN
/ CONNECT MODE.
/ 024 19-NOV-1987 NEW FEATURES. CJL
/ NEW STARTUP MESSAGES AND HELP METHOD VIA COMMAND. CPU TYPE
/ IDENTIFICATION TO ALLOW FUTURE VERSIONS TO CHECK FOR QUIRKS AND
/ MODEL DEPENDENCIES. THE DEFAULT PROMPT REFLECTS THE ACTUAL CPU
/ TYPE (THUS "KERMIT-12>" ON PDP-12). VERSION, REVISION, AND DATE
/ NOW EQUATED SYMBOLS.
/ 023 18-NOV-1987 NEW CONSOLE I/O PACKAGE. CJL
/ NEW CONSOLE I/O ROUTINES WITH DC1/DC3 SUPPORT FOR CONSOLE
/ TERMINAL MESSAGES NOT ASSOCIATED WITH ANY REMOTE ACTIVITY (NOT TO
/ BE USED DURING CONNECT MODE). USES FIELD ONE FOR MESSAGE TEXT TO
/ ALLOW FOR MORE PROGRAM SPACE. THE MESSAGES ARE NOW GIVEN IN
/ UPPER/LOWER SIXBIT FORMAT. SUPPORT FOR <^P> RESTART AND <^O> TO
/ FLIP ECHO. UPPER-CASE CAN BE FORCED BY CHANGING A VARIABLE
/ ('UPONLY').
/ 022 17-NOV-1987 BUG FIX. CJL
/ EXTRA-LONG INIT PACKETS CORRUPTING PROGRAM; NOW CHECKS FOR AND
/ IGNORES EXTRA CAPABILITIES BEYOND 'CAPAS' BYTE.
/ 021 17-NOV-1987 CODE CLEANUP. CJL
/ REWROTE TENTATIVE OUTPUT FILE LENGTH CODE FOR MORE CONSISTENCY.
/ RENAMED "FINISH" COMMAND CORRECTLY (FORMERLY "BYE").
/ FORMER CODE REGARDING THE TENTATIVE FILE MAXIMUM LENGTH WAS ACCEPTABLY
/ ORGANIZED FOR ORIGINAL PS/8, OS/8 CONVENTIONS. WITH THE EVOLUTION OF THE
/ OPERATING SYSTEM INTO OS/78 (VERSIONS 1-4) AND OS/278 (VERSIONS 1-2), THE
/ ENTER OPERATION HAS BEEN CHANGED WITH DANGEROUS CONSEQUENCES.
/ THE ORIGINAL DEFINITION OF THE LENGTH RETURNED BY ENTER IS THE ACTUAL LENGTH
/ OF THE LARGEST EMPTY (IN TWO'S COMPLEMENT FORM). IF RECORD 7777 IS PART OF
/ THE ACTUAL LARGEST EMPTY (FULL SIZE DEVICE AND THE LARGEST EMPTY IS LAST ON
/ THE DEVICE), THEN THE LENGTH RETURNED IS ONE LESS (THIS IS A LONG STANDING
/ BUG). SINCE THERE IS NO STRAIGHT-FORWARD WAY TO DETERMINE THIS, THE LENGTH IS
/ ASSUMED TO BE CORRECT.
/ TESTS WITH THE DECUS VERSION OF OS/278 (DM-101) REVEAL A DANGEROUS CHANGE:
/ THE LENGTH RETURNED IS TWO LARGER THAN ACTUALLY EXISTS!
/ TO COUNTERACT THIS, EDIT 010 INSERTED A DECREMENT OF TWO INTO THE LENGTH
/ BEFORE PASSING IT BACK TO THE KERMIT FILE WRITING ROUTINE. THE FILE WRITING
/ ROUTINE THEN ADDS ONE TO THE LENGTH TO CREATE A "DANGER COUNT", I.E., IN TWO'S
/ COMPLEMENT NOTATION, THIS IS THE AMOUNT THAT WILL INDICATE FILE OVERFLOW
/ SHOULD IT REACH ZERO.
/ THIS HAS NOW BEEN REORGANIZED TO ALLOW THE ENTER ROUTINE TO SET THE DANGER
/ COUNT DIRECTLY. OS/8 USERS MUST ALLOW FOR THE EXTRA ROOM (WHICH MUST BE
/ PRESENT BUT WILL NOT BE USED), SINCE NO CHECK FOR SYSTEM VERSION WILL BE
/ PERFORMED.
/ 020 16-NOV-1987 NEW ROUTINES AND CODE CLEANUP. CJL
/ REWROTE ENTIRE OUTPUT FILE PACK ROUTINE. NOW SUPPORTS
/ ASCII/BINARY INTERNAL FILE MODE FOR LATER USE. USES OUTPUT
/ BUFFER IN FIELD ONE (SAME DEFINITIONS AS INPUT BUFFER) TO ALLOW
/ MORE PROGRAM SPACE. END OF FILE CONVENTION IN ASCII MODE NOW
/ INCLUDES ENSURING <^Z> CHARACTER PACKED INTO FILE (OR NOT).
/ REWROTE ENTIRE OUTPUT FILE CLOSE ROUTINE TO IMPLEMENT <^Z>
/ SCHEME. ELIMINATED SEPARATE OUTPUT FILE INITIALIZE ROUTINE; USE
/ SPECIAL ROUTINE CALL INSTEAD. FIXED PACKET WRITE BUG.
/ 019 15-NOV-1987 NEW ROUTINES AND CODE CLEANUP. CJL
/ FIXED UNPACK <^Z> BUG. REWROTE ENTIRE INPUT FILE UNPACK ROUTINE.
/ NOW SUPPORTS ASCII/BINARY INTERNAL FILE MODE FOR LATER USE. USES
/ INPUT BUFFER IN FIELD ONE TO ALLOW MORE PROGRAM SPACE. BUFFER
/ FIELD DEFINED VIA SYMBOLS TO ALLOW CHANGES IN THE FUTURE. END OF
/ FILE CONVENTION IN ASCII MODE NOW INCLUDES SENDING <^Z> CHARACTER
/ OR NOT. ELIMINATED SEPARATE INPUT FILE INITIALIZE ROUTINE; USE
/ SPECIAL ROUTINE CALL INSTEAD.
/ 018 09-NOV-1987 BUG FIX AND CODE CLEANUP. CJL
/ FIXED RECEIVE BUG; NOW ALLOW DEV: ON RECEIVE.
/ 017 05-NOV-1987 NEW FEATURES. CJL
/ CONDITIONAL ASSEMBLY PARAMETERS ADDED FOR MACHINE TYPE (PDP-8,
/ DECMATE I, DECMATE II/III/III+), REMOTE LINE AND LOCAL TERMINAL
/ INTERFACE DEFINITIONS.
/ 016 05-NOV-1987 CODE CLEANUP. CJL
/ OPTIMIZATION OF CODE, LITERALS, CONSTANTS.
/ 015 04-NOV-1987 BUG FIX. CJL
/ INPUT SERVICE ROUTINE ERROR DOES JMP INSTEAD OF JMS WHEN CALLING
/ COMMON ERROR HANDLER.
/ 014 02-NOV-1987 SOURCE FILE CLEANUP. CJL
/ SOURCE FILE COSMETICALLY CLEANED UP AND RENAMED TO K12MIT.PAL
/ WHICH CONFORMS WITH CUCCA NAMING CONVENTION. NO ACTUAL BINARY
/ CODE CHANGES BEYOND K08V2. THIS EDIT HISTORY ADDED. ENTRIES
/ PRIOR TO 014 TRANSCRIBED BY CJL.
/ SINCE THE PDP-12 (AND OTHER 12-BIT DEC MACHINES) IS THE INTENDED ENVIRONMENT
/ FOR THIS PROGRAM, IT IS NOW KNOWN AS KERMIT-12.
/ ASSEMBLING THE SOURCE FILE PRODUCES BINARY IDENTICAL TO K08V2.PA CONFIRMING
/ THAT SOURCE CLEANUP DOESN'T DAMAGE THE CODING (K08V2 IS NOW OBSOLETE).
/ 013 01-OCT-1987 CHANGE TO VERSION 2.0. R. SCHLERF (RICH)
/ CHANGED 'RKIOT'/'RTIOT' TO 43/44 REMOTE LINE IOT (LOCAL
/ PREFERENCE). CHANGED 'ESCAPE' CHARACTER TO ^] ('CONX1') FOR
/ GENERIC CONFORMITY. ADDED VERSION/COMMAND BANNER AT STARTUP FOR
/ MINI-HELP. INCORPORATED K278 CHANGES 003-006, 009-010 (NO
/ INTERRUPTS). DELETED 'ERRMSG.' NOW USES 'STXERR' AT 'CLOOP9'+2
/ FOR PROGRAM SPACE. TO CONFORM TO GENERIC KERMIT, "BACK ON PDP8"
/ MESSAGE DELETED AND REPLACED WITH BEEP <^G>. MESSAGE "SENDING
/ FILE XXXXXX.XX CREATED ON DD-MM-YY" REDUCED TO "SENDING FILE
/ XXXXXX.XX" TO CONFORM TO GENERIC KERMIT. PARITY BIT IS IGNORED
/ ON BOTH REMOTE AND TTY LINES. OUTPUT PARITY IS SET TO SPACE.
/ PROGRAM RENAMED TO K08V2.PA AND MADE AVAILABLE TO CUCCA BY:
/ RICHARD SCHLERF (RICH)
/ AMERICAN CYANAMID COMPANY
/ MEDICAL RESEARCH DIVISION
/ LEDERLE LABORATORIES
/ BUILDING 190 ROOM 115H
/ PEARL RIVER, NEW YORK 10965
/ (914) 732-2186 (09:00 TO 16:00)
/ SINCE PRIMARY APPLICATION OF K08V2 IS FOR PDP-8 USAGE, THE MODIFICATIONS NOT
/ SPECIFIC TO DECMATE II/III FROM K278 WERE MOVED TO THE K08MIT VERSION. FUTURE
/ VERSIONS WILL INCORPORATE THE DECMATE FEATURES AND THUS OBSOLETE ALL OTHER
/ VERSIONS AT THAT TIME.
/ 012 04-JUN-1986 PROGRAM FIX. SEPP STADELMANN (SSTA)
/ RE-INITIALIZE VIA 'V30ST' AS ROM SETUP CLEARS COMPOSETABLE, ETC.

/ (617) 897-5111
/ CUCCA RENAMED FILES (KERMIT.PA AND KERCOM.PA) TO K278.PA AND K278COM.PA (WHICH
/ DOESN'T REALLY CONFORM TO THE NAMING CONVENTION).
/ CUCCA VERSION OF K278.PA FOUND TO BE DEFECTIVE. FILE REPAIRED BY:
/ CHARLES LASNER (CJL)
/ CLA SYSTEMS
/ 72-55 METROPOLITAN AVENUE
/ MIDDLE VILLAGE, NEW YORK 11379-2107
/ (718) 894-6499
/ REPAIRED FILE (K278.PA) NOW AVAILABLE AT CUCCA.
/ PROGRAM IS NOW THE DECMATE II/III (III-PLUS) KERMIT ONLY. HOOKS WERE LEFT IN
/ FOR PDP-8 VERSION, BUT NOT IMPLEMENTED. K278 DOES WORK WITH ADDITIONAL
/ IMPLEMENTATIONS OF KERMIT, BUT RECEIVE COMMAND DOES NOT WORK. PROGRAM YIELDS
/ RECOVERABLE SYSTEM ERROR/HALT WHEN EXITING TO FLOPPY-BASED DECMATE II SYSTEM.
/ CONNECT MODE IS VT200 8-BIT WHICH CONFUSES EVEN/ODD PARITY SYSTEMS. K278 DOES
/ NOT SUPPORT SETUP KEY OF DECMATE, BUT IMPLEMENTS SETUP COMMAND.
/ 011 04-JUN-1986 NEW FEATURES. SSTA
/ 'PRQ3' CODE CONDITIONALS. ROM SETUP COMMAND IMPLEMENTED FOR DMII/III.
/ AUTOMATIC UPPERCASE SELECT ON RETURN FROM CONNECT.

/ KERMIT.PAL AND KERCOM.PAL ARE TWO SOURCE FILES ASSEMBLED TOGETHER TO PRODUCE
/ THE RUNNING KERMIT-8. *THEY ARE FOR THE DECMATE II/III/III-PLUS ONLY.*
/ 002 18-JUL-1985 ORIGINAL RELEASE. RANDY HIPPE
/ 18-JUL-1985 VERSION RELEASED TO CUCCA BY JERRY SANDS AND RANDY HIPPE OF:
/ BUREAU OF ENGRAVING, INC.
/ 3311 BROADWAY N.E.
/ MINNEAPOLIS, MN 55413
/ (612) 623-0900 X218
/ CUCCA RENAMED FILE (KER8.PAL) TO K08MIT.PAL WHICH CONFORMS TO NAMING
/ CONVENTION OF KERMIT FILES.
/ K08MIT SUPPORTS CONNECT, BYE (REALLY FIN), EXIT, SEND, GET, RECEIVE ONLY.
/ PROGRAM PRONE TO GETTING "CONFUSED" AND OUTPUTS FILE DATE ATTRIBUTE BOTH AS
/ 'CAPAS' BYTE FEATURE AND ASCII TEXT INSERTED INTO CONTENTS OF FILE AHEAD OF
/ FILE DATA. COMMAND PROCESSOR ACCEPTS UPPER-CASE COMPLETE COMMANDS ONLY. <^C>
/ ABORT FEATURE TAKES VERY LONG TIME TO ACT (IF AT ALL!). MANY KERMITS WILL NOT
/ WORK WITH K08MIT; HOWEVER, K08MIT WAS TESTED SUCCESSFULLY WITH KERMIT-20.
/ 001 30-JUL-1984 FIRST VERSION (KER8.PAL). JERRY SANDS
/ HARDWARE HINTS AND KINKS.
/ KERMIT-12 REQUIRES THE FOLLOWING STANDARD OS/8 FAMILY CONFIGURATION:
/ PDP-8 FAMILY MEMBER WITH AT LEAST 8K MEMORY.
/ OS/8 SYSTEM DEVICE (WITH OS/8 FAMILY OPERATING SYSTEM RESIDENT).
/ KL8-COMPATIBLE CONSOLE INTERFACE.
/ 7/8-BIT ASCII EXTERNAL CONSOLE TERMINAL DEVICE (TTY:).
/ KL8-COMPATIBLE REMOTE INTERFACE TO OTHER KERMIT.
/ NOTE: ASSEMBLY PARAMETERS OF KERMIT-12 ALLOW FOR LOCAL KERMIT CONTROLLING
/ TERMINALS TO BE OTHER THAN THE PRIMARY OS/8 CONSOLE DEVICE. THE ACTUAL
/ HARDWARE MUST STILL CONFORM TO THE SAME REQUIREMENTS (THE DEVICE CODES WOULD
/ THEN BE USER-SPECIFIED AND DIFFER FROM THE STANDARD 03/04) AS THE STANDARD
/ CONSOLE INTERFACE AND TERMINAL.
/ SPECIAL DECMATE CONSIDERATIONS:
/ DECMATE USAGE IS USUALLY OBTAINED BY ASSEMBLING FOR THE STANDARD CONSOLE
/ DEVICE (03/04), AS THE BUILT-IN FIRMWARE/SLUSHWARE OF THE DECMATES IS
/ SUFFICIENTLY COMPATIBLE WITH THE PDP-8 HARDWARE FOR KERMIT-12'S REQUIREMENTS.
/ (THE ONLY OTHER ACCEPTABLE CONSOLE DEVICE ON THE DECMATE IS THE PRINTER PORT.)
/ DECMATE REMOTE COMMUNICATIONS PORTS ARE *RADICALLY* DIFFERENT FROM
/ KL8-COMPATIBLE PORTS. THESE ARE HANDLED AUTOMATICALLY BY ONCE-ONLY CODE WHICH
/ DETECTS THE USAGE OF KERMIT-12 ON THE SPECIFIC DECMATE SYSTEM, AND
/ SELF-CONFIGURATION AS APPROPRIATE. THERE IS ONE EXCEPTION TO THIS, NAMELY IF
/ THE COMMUNICATIONS PORT CODE IS ASSEMBLED FOR THE PRINTER PORT (32/33), THEN
/ THE PRINTER PORT, *NOT* THE COMMUNICATIONS PORT WILL BE USED. THE STANDARD
/ ASSEMBLY OF KERMIT-12 IS FOR A PDP-8 WITH DEVICE 40/41 COMMUNICATIONS PORT.
/ THIS DESIGNATED VERSION WILL SELF-CONFIGURE WHEN EXECUTED ON A DECMATE.
/ CONFIGURATION RESTRICTIONS:
/ WHEN INTERRUPTS ARE SUPPORTED AGAIN, DEVICES SUCH AS THE TD-8/E WON'T WORK.
/ THE NON-INTERRUPT VERSION SHOULD WORK TO 19200 BAUD ON THE PDP-8/E CPU, SO
/ THIS SHOULD NOT BE A PROBLEM. INTERRUPT-DRIVEN VERSIONS OF KERMIT-12 MUST BE
/ RUN ONLY ON SYSTEMS WHERE *ALL* INTENDED DEVICES CAN HAVE THEIR HANDLERS
/ INTERRUPTED BY THE CONSOLE AND REMOTE LINE INTERRUPT HANDLERS. WHEN IN DOUBT,
/ THE NON-INTERRUPT VERSION MUST BE USED (CURRENTLY THE ONLY VERSION).
/ IF FLOW CONTROL IS DISABLED (DUE TO XON/XOFF BEING UNAVAILABLE) THEN THE
/ CONSOLE BAUD RATE MUST MEET OR EXCEED THE REMOTE LINE RATE. THE USER MUST
/ TAKE MINIMAL CARE NOT TO OVERLOAD THE INTERNAL BUFFERS OF KERMIT-12, AS THIS
/ WILL YIELD THE ERROR MESSAGE: KEYBOARD INPUT ERROR!
/ THIS IS NOT LIKELY TO OCCUR UNLESS ONE "PLAYS" WITH A KEYBOARD WHICH CAN
/ GENERATE NUMEROUS ESCAPE SEQUENCES AS THE BUFFERS ARE QUITE ADEQUATE FOR ALL
/ REASONABLE TERMINAL APPLICATIONS. SIMILARLY, IF THE REMOTE LINE DOES NOT OBEY
/ XON/XOFF PROTOCOL (WHILE KERMIT-12 HAS IT ENABLED), THEN INTERNAL BUFFER
/ OVERFLOW WILL YIELD THE ERROR MESSAGE: REMOTE LINE INPUT ERROR!
/ THESE ERRORS ARE EXTREMELY UNLIKELY AND CAN ONLY BE CREATED BY MISUSE OF FLOW
/ CONTROL (THE ONLY EXCEPTION TO THIS IS THE ATTEMPT TO USE KERMIT-12 WITH THE
/ CONSOLE BAUD RATE SLOWER THAN THE REMOTE LINE BAUD RATE WITH FLOW CONTROL
/ DISABLED). IF FLOW CONTROL IS ENABLED AND OBEYED THEN THE BUFFERING OF REMOTE
/ LINE INPUT WILL OCCUR WHILE SHORT PAUSES OCCUR ON THE CONSOLE (ASSUMING THE
/ USER FREEZES/UNFREEZES THE DISPLAY OFTEN AND THE CONSOLE DISPLAY BAUD RATE IS
/ FASTER THAN THE REMOTE LINE BAUD RATE) WITH PRACTICALLY NO REMOTE LINE DELAY.
/ FLOW CONTROL IS NOT YET SUPPORTED DURING KERMIT TRANSFERS. SINCE KERMIT-12
/ DOES NOT SUPPORT SLIDING WINDOWS, KERMIT-12 WILL NEVER GENERATE OUTGOING
/ XON/XOFF SEQUENCES. FUTURE REVISIONS WILL SUPPORT INCOMING XON/XOFF FROM THE
/ REMOTE KERMIT. XON/XOFF PROTOCOL DURING CONNECT MODE IS COMPLETELY AVAILABLE
/ AT THE USER'S OPTION.
/ CONSOLE TERMINALS ARE REQUIRED TO SUPPORT "GLASS TTY:" FEATURES, I.E. THE
/ PRINTING ASCII CHARACTER SET (LOWER-CASE DESIRABLE) AND THE CONTROL CHARACTERS
/ <CR>, <LF>, AND <BEL> (THE LAST FOR VARIOUS AUDIBLE REPORTS ONLY). TERMINALS
/ LACKING LOWER-CASE SUPPORT SHOULD "FOLD" LOWER-CASE CHARACTERS TO UPPER-CASE
/ AUTOMATICALLY. TERMINALS SUCH AS THE VT05 CAN HAVE THE KEYBOARD LOWER-CASE
/ ENABLED, AS KERMIT-12 SUPPORTS OPTIONAL OUTPUT FOLDING. THE UPPER-CASE ONLY
/ OPTION SHOULD BE ENABLED FOR TERMINALS WHICH IGNORE LOWER-CASE INPUT FROM THE
/ HOST, AS KERMIT-12 GENERATES NUMEROUS LOWER-CASE MESSAGE CHARACTERS (WHICH
/ BECOME UPPER-CASE IF THIS OPTION IS SET). THE <BS> CHARACTER IS REQUIRED FOR
/ VISUAL RUBOUT (<BS> <SPACE> <BS>) ONLY. FUTURE VERSIONS WILL SUPPORT
/ HARD-COPY BACKSPACE TO REMOVE THIS REQUIREMENT. ALL TERMINAL FEATURES (SUCH
/ AS ACTUAL VT-100 FUNCTIONALITY) ARE FREELY PASSED TO THE HOST DURING CONNECT
/ MODE; THE ONLY CHARACTER ACTUALLY RESERVED IS THE ESCAPE CHARACTER WHICH WILL
/ BE TREATED AS A SEVEN-BIT CHARACTER ONLY. IF THE USER PRESSES THE ESCAPE
/ CHARACTER TWICE, THEN THE SEVEN-BIT REPRESENTATION OF THE CHARACTER IS SENT
/ ONCE; THERE IS NO WAY TO SEND THE ESCAPE CHARACTER WITH THE HIGH-BIT SET.
/ SINCE THE ESCAPE CHARACTER ITSELF CAN BE SET TO ALMOST ANY SEVEN-BIT VALUE,
/ THIS SHOULD NOT BE A SERIOUS LIMITATION. TERMINALS THAT DON'T "BEEP" WHEN THE
/ <BEL> CHARACTER IS SENT SHOULD NOT OUTPUT A PRINTABLE RENDITION OF THE <^G>
/ CHARACTER, AS THIS WOULD DISRUPT THE TERMINAL OUTPUT AND INTERNAL COLUMN COUNT
/ DURING VARIOUS MESSAGE SEQUENCES, ETC.
/ KL-8/E INTERFACES SHOULD BE SETUP WITH THE FOLLOWING STANDARD SETTINGS:
/ 1 STOP BIT ABOVE 110 BAUD WITH 8 BITS DATA.
/ FUNCTIONAL BAUD RATES INCLUDE 110, 150, 300, 600, 1200, 2400, 4800, 9600,
/ 19200, 38400 AND 76800. 2400 BAUD REQUIRES A REVISION "B" OR BETTER M8650
/ MODULE (IF ONE USES DEC'S DOCUMENTATION OF AVAILABLE SPLIT-LUG OPTIONS).
/ ACTUAL BAUD RATES UP TO APPROXIMATELY 100 KBAUD SHOULD WORK WHEN KERMIT-12
/ BECOMES INTERRUPT-DRIVEN. RATES OTHER THAN 110 BAUD REQUIRE A 19.6608 MHZ
/ BAUD-RATE OSCILLATOR.
/ THE BAUD RATES STATED ABOVE ARE ACTUALLY AVAILABLE ON THE KL-8/E, BUT REQUIRE
/ A SINGLE SOLDER JUMPER TO IMPLEMENT THE PROPER BAUD RATE ABOVE 2400 BAUD.
/ CHANGING BAUD-RATE GENERATOR CRYSTALS WILL PRODUCE OTHER RATES AS NECESSARY.
/ (SEND INQUIRIES TO CLA SYSTEMS FOR INFORMATION REGARDING KL-8/E MODIFICATIONS
/ INCLUDING UPGRADED BAUD-RATE OSCILLATORS, ETC.) KERMIT-12 HAS BEEN TESTED TO
/ 9600 BAUD AND SHOULD WORK TO 19200 BAUD (AS OF THE CURRENT VERSION).
/ KL8-J/A INTERFACES SHOULD BE SETUP WITH THE FOLLOWING STANDARD SETTINGS:
/ 1 STOP BIT ABOVE 110 BAUD WITH 8 BITS DATA NO PARITY.
/ FUTURE VERSIONS OF KERMIT-12 WILL SUPPORT VARIOUS SOFTWARE-GENERATED PARITY
/ OPTIONS. THE FRAMING AND OVERRUN ERRORS CAN BE ENABLED AND WILL EVENTUALLY BE
/ SUPPORTED (BUT THE PARITY GENERATOR SHOULD BE DISABLED TO PREVENT INTERACTION
/ WITH THE SOFTWARE USE OF PARITY GENERATION/DETECTION).
/ ALL BAUD RATES ARE SUPPORTABLE:
/ 110, 150, 300, 600, 1200, 2400, 4800, 9600, 19200.
/ 19200 BAUD IS ACHIEVED BY CUTTING JUMPER "W2" AND ADDING JUMPER "W5" AND THEN
/ SETTING THE BOARD FOR WHAT IS NORMALLY 9600 BAUD. A WESTERN DIGITAL TR-1602-B
/ OR EQUIVALENT UART IS REQUIRED TO SUPPORT 19200 BAUD; MOST OF THE RECENT
/ PRODUCTION DEC M8655 BOARDS USE THE SMC COMM 2017 UART WHICH MEETS OR EXCEEDS
/ THIS REQUIREMENT. EARLY M8655 BOARDS USE GI UARTS IN CERAMIC PACKAGES WHICH
/ *CANNOT* BE USED AT 19200 BAUD (MANY ARE FLAKY AT 9600 BAUD!).
/ RECEIVE BAUD RATE SHOULD BE IDENTICAL TO TRANSMIT BAUD RATE. (DO NOT SET THE
/ RECEIVE=150 BAUD SWITCH!)
/ OTHER INTERFACES:
/ DKC-8/A (8/A OPTION BOARD #1) INTERFACES SHOULD BE SETUP AS PER THE KL8-J/A
/ SPECIFICATIONS INCLUDING THE REQUIREMENTS OF THE UART. SOME DEC DOCUMENTATION
/ INDICATED A PROHIBITION ON THE USE OF 19200 BAUD, BUT THIS IS OBVIATED BY THE
/ USE OF THE SAME UARTS AS IN THE KL8-J/A.
/ EARLIER DEVICES SUCH AS PT08, DP-12, KL-8/F OR DC02 (CHANNEL ZERO ONLY) SHOULD
/ WORK CORRECTLY AS FACTORY WIRED (MOST OF THESE DEVICES DO NOT SUPPORT OPTIONS
/ KERMIT-12 WOULD REQUIRE TO BE DISABLED ANYWAY. THESE INCLUDE PARITY
/ GENERATION, FRAMING ERROR DETECTION, ETC.). TO UTILIZE THESE DEVICES, THE
/ ASSEMBLY PARAMETERS FOR USER DEVICES AND THEIR RESPECTIVE DEVICE CODE VALUES
/ SHOULD BE GIVEN DURING ASSEMBLY (SEE ASSEMBLY INSTRUCTIONS). PROPER DEVICE
/ CODE VALUES MUST BE OBTAINED FOR THE SELECTED INTERFACE, AS THERE ARE MANY
/ ACTUAL POSSIBILITIES. (DP-12 DEVICES ARE GENERALLY DEVICE 40/41; PT08/DC02
/ INTERFACES ARE GENERALLY DEVICE 11/12, ETC.)
/ ASSEMBLY INSTRUCTIONS.
/ KERMIT-12 CAN BE ASSEMBLED BY EITHER OF TWO METHODS:
/ P?S/8 METHOD:
/ ASSUMING THE EXTENDED-LENGTH FILE KERM12 IS THE SOURCE FILE, THE FOLLOWING
/ COMMAND WILL PRODUCE A FULLY ORNAMENTED LISTING:
/ .PAL KB1,KB2,KB3,KB4<KERM12(ACEJLMNPQSX8)
/ OPTION SWITCH BREAKDOWN:
/ /A ALL SYMBOLS IN SYMBOL PRINTOUT.
/ /C OPTIMIZE CORE DURING ASSEMBLY FOR MORE SYMBOLS, LESS BUFFERS.
/ THIS OPTION SHOULD BE DELETED IF MORE THAN 8K IS AVAILABLE FOR
/ ASSEMBLY.
/ /E FORGET LITERAL BOUNDARIES WHEN LEAVING THE CURRENT PAGE.
/ /J *DO NOT* TERMINATE TEXT STRINGS WITH EXTRA ZERO WORD.
/ /L PERFORM SECOND-PASS LISTING.
/ /M CHAIN TO MAP FOR BITMAP OUTPUT AT END OF ASSEMBLY.
/ /N ENABLE NEATNESS ADORNMENTS TO LISTING OUTPUT.
/ /P ENABLE PRINTER-ORIENTED (WIDE MODE) LISTING OUTPUT.
/ /Q ENABLE LITERALS ONLY, GENERATED LINKS ARE ERRORS.
/ /S ENABLE SYMBOL TABLE PRINTOUT.
/ /X ENABLE CROSS-REFERENCE OUTPUT AT END OF ASSEMBLY.
/ /8 ENABLE FULL SYMBOL TABLE INCLUDING LINC MODE CROSS ASSEMBLY.
/ THE NUMBER OF BINARY FILES REQUIRED (KB1, KB2, KB3, ETC.) IS TO BE DETERMINED
/ AT ASSEMBLY TIME, AS KERMIT-12 WILL TEND TO GROW LARGER AS FEATURES ARE ADDED.
/ P?S/8 PAL IS THE PREFERRED METHOD OF ASSEMBLING K12MIT DURING DEVELOPMENT DUE
/ TO SUPERIOR ERROR DIAGNOSTICS AND OVERALL SPEED. K12MIT COULD GROW TO A SIZE
/ BEYOND THE CAPABILITIES OF OS/8 CREF. THIS LIMITATION CANNOT APPLY TO THE
/ P?S/8 DEVELOPMENT ENVIRONMENT.
/ P?S/8 PAL CAN PRODUCE A LISTING OF K12MIT, BUT THE BINARY FILES CREATED BY THE
/ ASSEMBLY MUST BE TRANSFERRED TO AN OS/8 ENVIRONMENT FOR USE, SINCE K12MIT (AS
/ SPECIFICALLY WRITTEN) IS FOR THE OS/8 FAMILY OF SYSTEMS ONLY.
/ NOTE: P?S/8 IS *NOT* A DEC PRODUCT; IT IS SOLD COMMERCIALLY AND IS AVAILABLE
/ FREE OF CHARGE (EXCEPT FOR MEDIA HANDLING CHARGES, ETC.) *ONLY* TO QUALIFIED
/ INSTITUTIONS. CONTACT CJL FOR ADDITIONAL INFORMATION ON ACQUIRING P?S/8.
/ OS/8 FAMILY OF SYSTEMS METHOD:
/ K12MIT.PA CAN BE ASSEMBLED WITH PAL8 VERSION B0 WHICH IS AVAILABLE FROM DECUS
/ AS PART OF THE OS/278 RELEASE. PAL8 VERSION B0 WILL RUN ON ANY OS/8 FAMILY
/ SYSTEM, AS IT HAS NO HARDWARE DEPENDENCIES BEYOND THE ORIGINAL PDP-8
/ REQUIREMENT (NO BSW OR IAC ROTATE OR CAF OR R3L INSTRUCTIONS AS WAS INTENDED).
/ THIS ALSO APPLIES TO CREF VERSION B0 WHICH IS REQUIRED WHEN A CROSS-REFERENCE
/ IS REQUESTED. PAL8 VERSION B0 AND CREF VERSION B0 ARE AVAILABLE AS PART OF
/ THE KERMIT-12 DISTRIBUTION AS K12PL8.ENC AND K12CRF.ENC RESPECTIVELY. SEE THE
/ DOCUMENTATION OF K12DEC FOR INFORMATION ON PRODUCING PAL8.SV AND CREF.SV FROM
/ THESE ENCODED FILES.
/ ASSUMING CCL IS ENABLED, THE FOLLOWING COMMAND WILL PRODUCE A BINARY AND FULLY
/ ORNAMENTED LISTING:
/ .PAL DEV:K12MIT.BN,DEV:K12MIT.LS,DEV:KSCR.TM<DEV:PARAM.PA,DEV:K12MIT.PA(CEFMW)
/ DEV: IS THE APPLICABLE DEVICE WHERE THE FILES RESIDE. STANDARD EXTENSIONS
/ ARE ASSUMED (.BN FOR BINARY, .LS FOR LISTING, .PA FOR PAL SOURCE). THE
/ KSCR.TM TEMPORARY OUTPUT FILE SPECIFICATION IS OPTIONAL, BUT IS DEFAULTED TO
/ SYS:CREFLS.TM IF NOT EXPLICITLY GIVEN. MANY SYSTEM DEVICES ARE TOO SMALL TO
/ SUPPORT THIS TEMPORARY FILE, THUS THE FILE MAY BE DIRECTED TO ANOTHER
/ AVAILABLE DEVICE WITH SUFFICIENT SPACE.
/ THE PARAM.PA FILE IS OPTIONAL AND USED TO PASS SHORT USER PARAMETERS, ETC. TO
/ THE ASSEMBLY.
/ OPTION SWITCH BREAKDOWN:
/ /C CHAIN TO CREF.SV TO PRODUCE A CROSS-REFERENCED LISTING FILE.
/ /E GENERATED LINKS ARE ERRORS.
/ /F *DO NOT* TERMINATE TEXT STRINGS WITH EXTRA ZERO WORD.
/ /M USE MAMMOTH SYMBOL TABLE OPTION FOR CREF.
/ /W FORGET LITERAL BOUNDARIES WHEN LEAVING THE CURRENT PAGE.
/ LOADING INSTRUCTIONS:
/ .LOAD DEV:K12CLR,K12MIT.BN THIS LOADS THE BINARY CLEAR AND KERMIT
/ .SAVE DEV K12MIT.SV=1 THIS SAVES THE CORE IMAGE
/ THE JOB STATUS WORD (=1) INDICATED THAT K12MIT.SV LOADS INTO 10000-11777, BUT
/ SHOULD NOT BE SAVED/RESTORED WHEN THE USR IS LOADED OVER THIS AREA OR
/ DISMISSED (THE USR IS ACTUALLY NEVER DISMISSED IN NORMAL K12MIT OPERATION).
/ OTHER BITS MAY BE SET AT THE USER'S OPTION, BUT ARE UNNECESSARY; THE BIT
/ INDICATED SERVES ONLY TO REDUCE SYSTEM OVERHEAD REGARDING THE DISPOSITION OF
/ 10000-11777. THE BINARY FILE K12CLR.BN (CREATED BY ASSEMBLING K12CLR.PA)
/ LOADS ZEROES INTO ALL OF MEMORY TO CREATE A "CLEAN" CORE IMAGE FILE, WHICH
/ MAKES THE ENCODED BINARY FILE SMALLER DUE TO REPEAT COMPRESSION.
/ PASSING SHORT PARAMETER FILES.
/ WHEN INSERTING A SHORT USER MODIFICATION FILE IN THE INPUT STREAM (PARAM.PAL)
/ THE FOLLOWING SHOULD BE NOTED:
/ ALWAYS PUT THE SHORT PARAMETER FILE (CONTAINING EQUATED SYMBOLS SUCH AS
/ USER=1, ETC.) IN FRONT OF K12MIT.PAL.
/ IF TTY: IS USED FOR DIRECT TYPE-IN OF THESE PARAMETERS, THE INFORMATION NEED
/ ONLY BE TYPED ENDING WITH <^Z> DURING PASS 1. SUBSEQUENT PASSES REQUIRE THE
/ ENDING <^Z> ONLY. IF THIS METHOD IS USED, A LISTING WITHOUT THE USER INPUT
/ WHICH DID THE CUSTOMIZING OF KERMIT-12 CAN BE CREATED. NOTE: IF BINARY IS
/ GENERATED BY THE CONTENTS OF THE PARAMETER FILE (SUCH AS USE OF THE LOCAL TEXT
/ MESSAGE, ETC.), THE INFORMATION MUST BE TYPED IN DURING PASS 2. THE PASS 3
/ LISTING MAY CONTAIN THE INFORMATION IF SO DESIRED, REQUIRING A REPETITION OF
/ THE INPUT. PASS 1 INPUT OF THE INFORMATION IS EFFECTIVELY IGNORED, AS NO
/ DEFINITIONS ARE CREATED ('LCLMSG' IS DEFINED ELSEWHERE, ETC.).
/ EXPERIENCED PDP-8 USERS NEW TO PAL8 VERSION B0 TAKE SPECIAL NOTICE:
/ DUE TO HARDWARE LIMITATIONS OF THE DECMATES, THE KEYBOARD FLAG WILL BE CLEARED
/ DURING PDP-8 PAL8 B0 OPERATION. THE KL8E TTY: HANDLER WILL NO LONGER BE ABLE
/ TO BUFFER <^Z> DURING THE ASSEMBLY; YOU MUST WAIT UNTIL THE HANDLER ACCESSES
/ THE KEYBOARD ON EACH PASS *THEN* PRESS <^Z> TO CONTINUE THE ASSEMBLY.
/ CREATING A CUSTOM MESSAGE FROM THE PARAMETER FILE.
/ IF SO DESIRED, A CUSTOM LOCAL HEADER MESSAGE MAY BE ADDED BY INSERTING THE
/ FOLLOWING INTO THE PARAMETER FILE:
/ BUFFLD= 10 /THESE PROBABLY
/ FILBUFF=2000 /WON'T CHANGE!
/ GENMSG= 0 /DON'T GENERATE STANDARD (NULL) MESSAGE
/ UMSG= 0 /DON'T GENERATE STANDARD (DUMMY) USER MESSAGE
/ FIELD BUFFLD%10 /FIELD FOR TEXT MESSAGE
/ *FILBUFFER /LOCAL MESSAGE LOADS THERE
/LCLMSG,TEXT "%^I^NSERT ^L^OCAL ^M^ESSAGE ^H^ERE!%"
/ ZBLOCK LCLMSG+40-. /ZERO REST OF MESSAGE AREA
/ TEXT IS IN UPPER/LOWER-CASE SIXBIT WITH '^' MEANING SHIFT CASE (INITIALLY
/ LOWER-CASE) AND '%' MEANING <CR>, <LF>.
/ OTHER METHODS:
/ KERMIT-12 *CANNOT* BE ASSEMBLED BY PAL10 (LAST KNOWN VERSION OF PDP-8
/ CROSS-ASSEMBLER FOR TOPS10 (142)) BECAUSE IT LACKS CERTAIN FEATURES:
/ DOES NOT SUPPORT 'RELOC' PSEUDO-OP.
/ DOES NOT SUPPORT PAGE ZERO REDEFINE (CAUSES "Z" ERROR ON SOURCE FILES WHICH
/ DON'T HAVE ERRORS WHEN ASSEMBLED BY EITHER P?S/8 PAL OR OS/8 PAL8).
/ INCORRECTLY HANDLES 'ZBLOCK' PSEUDO-OP (LEADS TO "Q" ERROR ON SOURCE FILES
/ WHICH DON'T HAVE ERRORS WHEN ASSEMBLED BY EITHER P?S/8 PAL OR OS/8 PAL8).
/ DOES NOT SUPPORT LITERAL "FORGETTING" (P?S/8 PAL OPTION /E OR OS/8 PAL8 OPTION
/ /W) WHICH IS REQUIRED FOR DEFINING OVERLAY AREAS, ETC.
/ DOES NOT SUPPORT TEXT WITHOUT ZERO WORD FILL (P?S/8 PAL OPTION /J OR OS/8 PAL8
/ OPTION /F FULFILLS THIS REQUIREMENT) WHICH IS REQUIRED FOR TEXT MESSAGES.
/ P?S/8 PAL IS AN IMPROPER SUPERSET OF PAL10. PAL10 SUPPORTS MACRO-8 MODE AS AN
/ OPTION AND AUTOMATIC FIELD DUMP BITMAPS; ALL OTHER KNOWN PAL10 FEATURES EXIST
/ IN P?S/8 PAL INCLUDING THE SUPPORT OF THE AUTOMATIC FIELD DUMP BITMAP
/ PSEUDO-OPS ('ENBITS' AND 'NOBITS').
/ OS/8 PAL8 (VERSION B0) IS A SUBSET OF P?S/8 PAL WHICH HAS SEVERAL SYNTACTIC
/ QUIRKS (WHICH ARE AVOIDABLE, BUT NONETHELESS ARE INCOMPATIBLE WITH BOTH P?S/8
/ PAL AND PAL10 IN CERTAIN MINOR WAYS); REGARDLESS, PAL8 LACKS THE
/ COMPATIBILITY PROBLEMS OF PAL10.
/ MAINTAINING SOURCE COMPATIBILITY.
/ KERMIT-12 SOURCE FILE CONVENTIONS DEMAND THE USE OF THE COMMON SUBSET OF P?S/8
/ PAL AND OS/8 PAL8 (VERSION B0). CERTAIN FORMS OF STATEMENTS SHOULD BE
/ AVOIDED:
/ TAD /NOT LEGAL IN PAL8
/ 0+TAD /NOT LEGAL IN PAL10, AND POSSIBLY WRONG IN PAL8
/ TAD (3)+1 /GENERATES SAME AS "TAD (3+1)" IN PAL8
/ -A!-B /UNARY OPERATOR HANDLED WRONG IN PAL8
/ I+N /NOT LEGAL IN PAL8
/ N+I /NOT LEGAL IN PAL8
/ I I /NOT LEGAL IN PAL8
/ THIS REQUIREMENT IS EASILY MET BY KERMIT-12 AS MOST OF THESE CASES ARE
/ ESOTERIC QUIRKS AND NOT NEEDED FOR THIS ASSEMBLY.
/ THE RESTRICTIONS OF PAL10 (EVEN THOUGH IT HAS OTHER DESIRABLE FEATURES, MOST
/ OF WHICH IT SHARES WITH P?S/8 PAL) ARE TOO SEVERE TO ALLOW USABLE ASSEMBLY OF
/ THIS PROGRAM. BETTER CROSS-ASSEMBLERS MAY EXIST ELSEWHERE WHICH ARE
/ SOURCE-COMPATIBLE WITH KERMIT-12.
/ USE OF P?S/8 LANGUAGE EXTENSIONS.
/ P?S/8 OFFERS SEVERAL USEFUL FEATURES OVER PAL8 (AND PAL10) WHICH MAY BE USEFUL
/ FOR ASSEMBLY DEVELOPMENT OF KERMIT-12. THESE INCLUDE LANGUAGE ELEMENTS SUCH
/ AS "TAD (3)+1" HANDLED CORRECTLY, OR PSEUDO-OPS SUCH AS "PAUSE EXPR" WHERE THE
/ VALUE OF 'EXPR' WILL BE DISPLAYED ON THE SYSTEM CONSOLE DURING THE ASSEMBLY
/ WHEN THAT POINT IN THE ASSEMBLY IS REACHED. TO ACCESS THESE FEATURES AND
/ STILL PROVIDE COMPATIBILITY WITH PAL8 (VERSION B0), THE FOLLOWING CODING
/ TECHNIQUE IS SUGGESTED:
/ IFNDEF PQS <PQS=0> /WILL BE 0 ON PAL8, PAL10
/ IFZERO PQS < /DO PAL8, ETC. STUFF HERE
/ FOO= (TABLE) /DEFINE POINTER TO ADDRESS OF TABLE
/ TAD FOO-1 /GET (POINTER TO ADDRESS OF TABLE)-1
/ DCA XR1 /SETUP AUTO-INDEX REGISTER
/ WISH WE HAD PAUSE AND ERROR PSEUDO-OPS IN PAL8.
/ > /END OF PAL8, ETC. VARIANT
/ IFNZRO PQS < /DO P?S/8 PAL STUFF HERE
/ TAD (TABLE)-1 /GET (POINTER TO ADDRESS OF TABLE)-1

/ PASS= PASS+1 /BUMP EVERY ASSEMBLER PASS
/ PAUSE PASS /DISPLAY PASS NUMBER
/ IFNZRO .&4000 <
/ ERROR 1234 /DISPLAY ERROR MESSAGE IF THERE ARE PROBLEMS
/ >
/ > /END OF P?S/8 PAL VARIANT
/ THIS ALLOWS TEMPORARY DEVELOPMENT FEATURES OR PERMANENT ELEMENTS WHICH MAY BE
/ MORE ELEGANTLY EXPRESSED IN P?S/8 PAL VARIANT CODING, WHILE THE PAL8 (VERSION
/ B0) VERSION CAN STILL BE USED (VIA DIRECT OCTAL, MULTIPLE EQUATE STATEMENTS,
/ CONDITIONAL FLUSH AS IN THE ABOVE EXAMPLE, ETC. AS NECESSARY) FOR STANDARD
/ ASSEMBLY OF KERMIT-12.
/ ASSEMBLY PARAMETERS.
/ SEVERAL PARAMETERS MUST BE CHANGED WITHIN K12MIT.PA (OR PASSED TO THE
/ ASSEMBLER VIA A SHORT FILE INSERTED INTO THE ASSEMBLY STREAM BEFORE THE MAIN
/ FILE):
/ SETTING KEY= [RECEIVE IOT CODE FOR CONSOLE KEYBOARD] DEFINES THE CONSOLE
/ KEYBOARD IOT CODE (DEFAULT IS 03).
/ SETTING TTY= [TRANSMIT IOT CODE FOR CONSOLE OUTPUT] CHANGES THE CONSOLE
/ PRINTER IOT CODE (DEFAULT IS 04).
/ THE FOLLOWING DEFINITIONS ARE ESSENTIALLY FOR KL8-TYPE DEVICES ONLY, AS THE
/ CODE DEMANDS KL8 HARDWARE COMPATIBILITY. MODELS OTHER THAN PDP-8 (SUCH AS
/ DECMATE) GENERALLY EITHER PLACE RESTRICTIONS ON AVAILABLE INTERFACES (OTHER
/ SOFTWARE DESIGNATES A SERIAL INTERFACE AS A LOGICAL PRINTER PORT; DECMATES
/ SUPPORT A FIRMWARE "PRINT SCREEN" KEY WHICH ENFORCES THIS.), OR DON'T ALLOW
/ USABLE PLUG-IN OPTIONS.
/ IGNORING BUILT-IN DECMATE SUPPORT, THE FOLLOWING PARAMETERS ARE ACTIVE:
/ SETTING DEV30= 1 CREATES DEVICE 30/31 REMOTE LINE IOTS.
/ SETTING DEV40= 1 CREATES DEVICE 40/41 REMOTE LINE IOTS.
/ SETTING LEDERLE=1 CREATES DEVICE 43/44 REMOTE LINE IOTS (AND A CUSTOM
/ HEADER).
/ SETTING ORIGNAL=1 CREATES DEVICE 33/34 REMOTE LINE IOTS (ORIGINAL
/ SETTINGS).
/ SETTING SPRINT= 1 CREATES DEVICE 32/33 REMOTE LINE IOTS (SERIAL PRINTER
/ PORT).
/ SETTING USER= 1 CREATES DEVICE XX/XY REMOTE LINE IOTS.
/ IF NONE OF THESE ARE SET, THEN DEV40=1 APPLIES BY DEFAULT.
/ SETTING USER= 1 REQUIRES THE USER TO DEFINE TWO ADDITIONAL VALUES:
/ XX= [RECEIVE IOT DEVICE CODE] (DEFAULT IS 40).
/ XY= [TRANSMIT IOT DEVICE CODE] (DEFAULT IS 41).
/ SETTING SPRINT= 1 INHIBITS THE BUILT-IN CHECK FOR DECMATE OPERATION AND
/ USES THE SERIAL PRINTER PORT FOUND ON ALL
/ WPS-8-CONFIGURED PDP-8/E, PDP-8/A CONFIGURATIONS,
/ VT-78, AND ALL DECMATES (VT-278, DECMATE II, III,
/ III+) FOR REMOTE COMMUNICATIONS.
/ THE USE OF THE SERIAL PRINTER PORT FOR REMOTE COMMUNICATIONS PURPOSES MAY BE
/ PROBLEMATIC DUE TO CONSIDERATIONS SUCH AS THE RS-232 CONNECTION TO THE PRINTER
/ IS A MODEM (DCE), RATHER THAN A TERMINAL (DTE) (DECMATE II, ETC. REQUIRES A
/ GENDER CHANGER.), OR THE SOFTWARE DESIGNATION OF THE PORT AS BEING ALLEDGEDLY
/ *ONLY* FOR A PRINTER, SUCH AS WHEN CERTAIN SYSTEMS SUPPORT THE "PRINT SCREEN"
/ KEY AS A SCREEN DUMP TO THE SERIAL PRINTER PORT, ETC. THESE ISSUES ARE NOT
/ RELEVANT TO KERMIT-12 OPERATION, AS THE "PRINT SCREEN" KEY IS NOT SUPPORTED BY
/ KERMIT-12 IN THIS CONFIGURATION AS SUCH (FUTURE VERSIONS COULD REDEFINE THE
/ "PRINT SCREEN" KEY TO SUCH FUNCTIONS AS DUMP SCREEN TO A FILE, ETC.).
/ SETTING BRATE= NN SETS THE DEFAULT BAUD RATE (FOR SYSTEMS THAT SUPPORT
/ THIS FEATURE) FROM A TABLE OF VALUES (0-15) AS
/ FOLLOWS:
/ NN BAUD RATE
/ 00 50
/ 01 75

/ SETTING FLOW= 0 DISABLES FLOW-CONTROL BY DEFAULT.
/ SETTING FMODE= 0177 SETS THE DEFAULT FILE MODE TO ASCII.
/ SETTING FMODE= 4377 SETS THE DEFAULT FILE MODE TO BINARY.
/ SETTING GENMSG= 0 CAUSES NO BINARY TO BE GENERATED WHERE 'LCLMSG' IS
/ DEFINED. THIS ALLOWS THE PARAMETER FILE (PARAM.PA) OR
/ SUBSEQUENT OVERLAY BY K12PCH.BN TO DEFINE THE LOCAL
/ HEADER MESSAGE. THIS PARAMETER SHOULD NOT BE SET
/ UNLESS ONE OF THESE METHODS IS USED, ELSE THE HEADER
/ MESSAGE WILL BE UNDEFINED. (NOTE: IF K12PCH.BN
/ GENERATES A HEADER MESSAGE, THEN THIS PARAMETER IS
/ UNIMPORTANT, AS K12PCH.BN OVERLAYS THE BINARY OF
/ K12MIT.)
/ SETTING GENMSG= 1 CAUSES A HEADER MESSAGE TO BE GENERATED. THE CONTENTS

/ WILL BE GENERATED.
/ SETTING ICLOSE= 1 ENSURES A <^Z> AT <EOF> OF ASCII INPUT FILES BY
/ DEFAULT.
/ SETTING ICLOSE= 0 CLOSES ASCII INPUT FILES AS RECEIVED BY DEFAULT.
/ SETTING INIECHO=0 CAUSES A FULL-DUPLEX CONNECT MODE STATE WITH NO LOCAL
/ CHARACTER ECHOING BY DEFAULT.
/ SETTING INIECHO=1 CAUSES A HALF-DUPLEX CONNECT MODE STATE WITH LOCAL
/ ECHO OF ALL CONSOLE CHARACTERS BY DEFAULT.
/ SETTING LOWER= 0 ALLOWS LOWER-CASE CONSOLE OUTPUT BY DEFAULT.
/ SETTING LOWER= -40 FOLDS LOWER-CASE CONSOLE OUTPUT TO UPPER-CASE BY

/ SETTING PORT= 0 CAUSES THE DP-278 PORT 0 TO BE USED IF KERMIT-12 IS
/ RUN ON A DECMATE 1 (ASSUMING SPRINT=0).
/ SETTING PORT= 1 CAUSES THE DP-278 PORT 1 TO BE USED IF KERMIT-12 IS
/ RUN ON A DECMATE 1 (ASSUMING SPRINT=0).
/ SETTING RETCNT= NNNN SETS THE PACKET RETRY COUNT TO NNNN BY DEFAULT.
/ SETTING UMSG= 0 PREVENTS THE LOCAL USER HEADER MESSAGE FROM BEING

/ KERMIT-12 FOR THE FAMILY OF 12-BIT DEC MACHINES.
/ BRIEF USAGE DESCRIPTION.
/ KERMIT-12 IS AN IMPLEMENTATION OF THE KERMIT PROTOCOL FOR THE FAMILY OF 12-BIT
/ DEC (AND COMPATIBLE) MACHINES GENERALLY KNOWN AS PDP-8 OR DECMATE.
/ AS OF THE CURRENT IMPLEMENTATION, THE FOLLOWING COMMANDS ARE EFFECTIVE:
/ 1. CONNECT (TO REMOTE SYSTEM AS TERMINAL).
/ 2. SEND FILESPEC (TO REMOTE RECEIVER OR SERVER).
/ 3. RECEIVE FILESPEC (FROM REMOTE SENDER).
/ 4. GET FILESPEC (FROM REMOTE SERVER).
/ 5. FINISH (SERVING).
/ 6. SETUP (ON DECMATE II/III/III-PLUS ONLY). **** NOT IMPLEMENTED ****
/ 7. EXIT (TO OPERATING SYSTEM).
/ 8. HELP (DISPLAYS HELP MESSAGE).
/ FILESPEC MAY BE ANY LOCAL (OS/8) FILE-STRUCTURED DEVICE:FILENAME.EXTENSION,
/ WHERE THE FILENAME AND EXTENSION WILL BE TRUNCATED TO 6 ALPHANUMERICS AND 2
/ ALPHANUMERICS RESPECTIVELY, AS NECESSARY (THIS IS REFERRED TO AS 6.2 FILENAME
/ FORMAT). THE DEVICE: FIELD IS OPTIONAL; ALL COMMANDS USING THE DEVICE:
/ FIELD FOR LOCAL DEVICE SPECIFICATION WILL USE THIS DEVICE AS THE SOURCE OR
/ DESTINATION AS NECESSARY FOR THE LOCAL FILES. IF THE DEVICE: FIELD IS
/ OMITTED, THE DEFAULT DEVICE DSK: WILL BE USED. THE ACTUAL DEVICE USED MAY BE
/ SELECTED BEFORE INVOKING KERMIT-12 BY USING THE OS/8 ASSIGN COMMAND:
/ .ASSIGN DEV DSK
/ WHERE DEV IS ANY AVAILABLE FILE-STRUCTURED DEVICE.
/ KERMIT-12 USES AN UNUSUAL SCHEME FOR ITS PROMPT: THE ACTUAL DEFAULT PROMPT
/ TEXT IS PARTIALLY TAKEN FROM THE ACTUAL MACHINE KERMIT-12 IS CURRENTLY
/ EXECUTING ON. FOR EXAMPLE, IF KERMIT-12 HAS DETERMINED THE CPU TYPE AS
/ PDP-8/E, THE PROMPT WILL BE:
/ KERMIT-8/E>
/ THIS ALLOWS KERMIT-12 USERS (WITH DIFFERENT CPU-TYPE MACHINES) TO DISTINGUISH
/ MESSAGES ORIGINATING FROM THE RESPECTIVE SYSTEMS. FUTURE VERSIONS WILL
/ SUPPORT USER PROMPT STRINGS TO ALLOW MORE DISTINCTIVE SYSTEM MESSAGES.
/ THE HELP OR CONNECT COMMANDS MAY BE USED TO DETERMINE THE CURRENT CONNECT MODE
/ ESCAPE CHARACTER.
/ COMMAND RESTRICTIONS.
/ THE SEND COMMAND ALLOWS DEVICE:FILENAME.EXTENSION (6.2) WITH WILD-CARD
/ SUBSTITUTION. A * MAY BE GIVEN FOR AN ENTIRE FIELD (EITHER FILENAME OR
/ EXTENSION OR BOTH) ONLY. A ? WILL MATCH ANY SINGLE CHARACTER WHICH MUST
/ EXIST IN THE ACTUAL FILENAME OR EXTENSION, UNLESS RIGHT-MOST IN THE FIELD.
/ ALL MATCHING FILES WILL BE SENT. NO OUTBOUND FILENAME (AS-NAME) FACILITY
/ EXISTS AT THIS TIME.
/ THE RECEIVE COMMAND ALLOWS OPTIONAL DEVICE: ONLY. *THE FILENAME AND
/ EXTENSION ARE NOT ALLOWED*. NAMES OF RECEIVED FILES WILL BE MODIFIED IF
/ NECESSARY TO CONFORM TO THE 6.2 FORMAT. *IMPLEMENTATION RESTRICTION* :
/ CERTAIN REMOTE FILENAMES CONTAINING NON-ALPHANUMERIC CHARACTERS MAY CAUSE
/ KERMIT-12 TO HASTILY ABORT THE TRANSMISSION AND RETURN TO COMMAND LEVEL.
/ THE GET COMMAND ALLOWS OPTIONAL DEVICE: TO DETERMINE DESTINATION OF THE
/ INCOMING FILES. THE OUTBOUND FILESPEC MUST CONFORM TO LOCAL CONVENTIONS
/ (FILENAME AND EXTENSION ARE NOT LIMITED TO 6.2 FORMAT; THE DEVICE: FIELD
/ WILL NOT BE SENT TO THE REMOTE KERMIT UNLESS IT IS ILLEGAL WITHIN OS/8

/ DECMATE II, ETC. PORT INITIALIZE ROUTINE. /048 CJL
/ THIS ROUTINE IS MOSTLY "DARK GREY MAGIC" WHICH IS PRIMARILY DERIVED FROM THE
/ "OFFICIAL" INFORMATION TAKEN FROM THE ONLY KNOWN DOCUMENTATION, THE DECMATE II
/ PROGRAMMER'S REFERENCE MANUAL: EK-DECM2-RM-001. VARIOUS EMPLOYEES OF DIGITAL
/ EQUIPMENT CORPORATION (A MULTI-NATIONAL COMPANY) HAVE ADDITIONALLY CONTRIBUTED
/ TO THIS EFFORT BY PROVIDING PORTIONS OF THE "SACRED SLUSHWARE NOTES" ON A NOT
/ NECESSARILY WILLING BASIS THROUGH THEIR RELEASED WORKS, SUCH AS, BUT NOT
/ LIMITED TO, THE SOURCES OF THE PARTICULAR VERSION OF KERMIT-8 KNOWN AS K278.
/ IT IS ASSUMED THAT THESE PEOPLE HAVE ACCESS TO BETTER DOCUMENTATION OF THE
/ HARDWARE, AND ESPECIALLY DOCUMENTATION OF THE THREE DIFFERENT MODELS OF
/ DECMATE (II, III, III+) THAT THESE ISSUES APPLY TO.
/ SINCE IT IS NOT KNOWN WHETHER THE K278, ETC. CODE IS SPECIFIC AND PRECISE, OR
/ MERELY SLOPPY, VARIOUS "QUIRKY" CODING TECHNIQUES HAVE BEEN LEFT "AS IS", WITH
/ COMMENTS REGARDING POTENTIAL VARIANCE WITH DOCUMENTATION NOTED WHERE
/ NECESSARY. THE ORDER OF ACCESS TO THE REGISTERS HAS BEEN LEFT INTACT IN CASE
/ OF POTENTIAL INTERACTION. SEVERAL CHANGES HAVE BEEN MADE BEYOND THIS WORK AS
/ A RESULT OF TRIAL-AND-ERROR, AND ALSO HAND DIS-ASSEMBLY OF SEVERAL DECMATE
/ DISKETTES' CONTENTS.
/ IT IS HOPED THAT FUTURE "NEGOTIATIONS" WITH DEC ALLOW FOR PROPER DISCLOSURE OF
/ THESE ISSUES TO AVOID POTENTIAL SOFTWARE FAILURES EVIDENT IN THESE ROUTINES
/ DUE TO LACK OF PROPER DOCUMENTATION.

/ THE DECMATE III HAS AN INTERNAL MODEM OPTION WHICH IS NOT AVAILABLE IN THE
/ DECMATE II. THE INTERFACE TO THIS DEVICE IS APPARENTLY SHARED WITH THE MPSCC
/ MODEM INTERFACE WE NORMALLY USE, SO THE REGISTER ACCESS MUST BE MORE CAREFULLY
/ DEFINED. THE APPARENT DIFFERENTIATION IS THE CURRENT VALUE OF THE DATA FIELD,
/ NAMELY EITHER FIELD 0 OR 1. IT IS NOT KNOWN WHETHER THE THREE-BIT VALUE OF
/ THE DATA FIELD IS SIGNIFICENT (PRESUMABLY FOR FUTURE EXPANSION), OR MERELY THE
/ DATA FIELD'S LOW-ORDER BIT IS USED, AS ALL KNOWN EXAMPLES OF ALLEDGEDLY
/ FUNCTIONAL CODE USE APPROPRIATE CDF 00 AND CDF 10 ONLY. APPARENTLY THE MODEM
/ INTERFACE IS REFERRED TO AS "A" AND THE MPSCC INTERFACE IS REFERRED TO AS "B".

/ (PRESUMABLY TO DISABLE IT). TO SATISFY THE ABOVE REQUIREMENT (WHATEVER THIS
