SUBTTL Edit history
;Edit Who What
;---- --- ----
;
; 2 JJF Add support for SHOW PENDING CONNECTS and
; SHOW HOST-INITIATED-CONNECTS commands. Incorporate
; KDO's fix for SHOW SESSIONS. Fix output of SHOW SESSIONS
; to be more Galaxy-like.
;
; 3 JJF Fix bug that caused LCPORN to blow ORION out of the water with
; an invalid message type. GCO 10556.
;
; 4 KDO Fix the length of the argument list. GCO 10574.
;
; 5 RBW Add "Port Name" Columns to the SHOW SESSIONS Display. Add
; other changes to make LCP compatible with TOPS-20. Fix
; minor bugs in SHOW HOST-INITIATED and SHOW PENDING commands.
;
; 6 RBW Move Version Number code to LCPTAB to keep TOPS-20 OPR
; happy. MAKE SURE VERSION NUMBERS GET UPDATED THERE!!
;
; 7 RBW Fix bug in SHOW PENDING-REQUESTS. If there are Reverse LAT
; connects, but none are pending, say so!
;
; 10 JJF Fix problems which caused SHOW SESSIONS and both flavors
; of SHOW HOST-INITIATED-CONNECTS to make ORION croak.
; 1. Remove all use of Preserved ACs except P1 from both
; routines.
; 2. Make sure that we re-call SHWPCS to get the status
; of the connect after doing a $TEXT. TF no longer has the
; valid status in it.
; 22-Apr-88 GCO:10623 QAR:T10L342:00033
;
; 11 GAS Update copyright notice
;
; 12 RBW/JJF Fix problem with SET SERVICE-NAME accepting names with
; spaces in them -- remove space from the break mask of
; acceptable characters.
; 1-Jun-88 GCO:10635
;
; 13 JJF Solve problem where LCP will get an ILM stopcode on the
; KS under TOPS-10. Insert code to see if the system
; has LAT support. If it doesn't, reject all LAT functions.
; 12-Oct-88 GCO:10659 SPR:10-36169
;
; 14 KDO Modify the SHOW CHARACTERISTICS display to display
; twenty characters worth of service name instead of six.
; 26-Oct-89 GCO:10679 SPR:10-36281
