Subject: BYE on Z-100 with PMMI modem

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.
