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) -------
