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).

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.

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.

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.

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.

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.
