PlouffeMessage forwarded from Irv Hoff to fix the PMMI ring-back function in MDM727-729. #: 83977 Sec. 0 - Communications Sb: #PMMI problem fixed 20-Mar-84 06:48:04 Fm: Irv Hoff 72365,70 To: Bob Plouffe 70220,113 (X) Found the problem with the PMMI ringback. My fault. When I fixed MDM727 for (0-9) numbers on redialing, and renumbered some labels, missed this one. However, it's still a bit of a flakey circuit, as we wait 7 seconds after dialing, hope it goes through all the exchanges and has rung once, then we hang up, wait 5 seconds and go back and redial. Call this MDM727-9.MOD SUBJECT : MDM727 - MDM729 MOD FOR PMMI USERS FOR RINGBACK NUMBERS FROM : IRV HOFF W6FFC DATE : 18 MAR 84 This mod affects just PMMI modems that are using MDM727 and later, including MDM728 or MDM729. Change one byte: 097F from 75 to 69 (then SAVE 73 sectors) The ringback circuit should then work normally. When I fixed MDM727 to allow redialing the new (0-9) numbers and changed some some labels, this one was overlooked, sorry. If changing the source code, make the following change: ;..... ; ; ; Hang up, redial and listen for dial tone ; RINGBK1: CALL HANGUP ;hang up the phone MVI B,RBWAIT ;wait 5 seconds before redialing.. CALL TIMER ;..for line to clear, etc. CALL DIALBGN ;disconnect, reconnect, wait for tone JNC DIAL12 ;go redial number JMP DIALAGN ;no dial tone heard ;..... ; - - - - - - - - - - - - - - - (next to last line was: JNC DIAL13 which was incorrect)
