From: Keith Petersen <W8SDZ@Simtel20.ARPA> A hint: I once troubleshooted a problem with a PMMI plug-in modem on a NorthStar Horizon system a friend owned. We found there was an address conflict with the Mother board. It uses C0h and the default settings for the PMMI when shipped from the factory are for C0h. We moved the PMMI to B0h and reassembled the MODEM program for that port address and all the problems went away. He was also able to sucessfully run BYE (although it was a very early BYE program called PMMIBYE2 which was specific for that modem). I suggest you have your friend try PMMIBYE2.ASM, which You'll find in the MICRO:<CPM.MODEM> directory. It isn't fancy like BYE3-19, but it does work. It would help a lot if he used this simple BYE first because it would make troubleshooting much easier. --Keith
