Subject: Potential configuration trap for MEX users

Info on potential trap for MEX users: Modem7 contained default code
for the PMMI modem in the user area.  Some overlays took advantage of
that when no change was required by placing DS's there instead of the
required ANI and CPI code.  No problem with Modem7, but MEX doesn't
work then because there is a RET NOP NOP there.  Two MXO overlays
ACTUALLY exist with this problem - they could never have worked! (Irv
strikes again?).  MXO-DP??.AQM and MXO-TV??.AQM.

I lost about two hours trying to figure that one out.  The program
locked up immediately because the ANI and CPI stuff was missing!
