Re:   MEX/Sanyo bug fix

MEX 1.0 has the same SANYO MBC-1000 glitch that the MDMxxx series 
has.  When a connection is made after continuous dialing both go 
to a loop doing KEYSTAT, WAIT, & BELL.  The routines in this 
order lock the keyboard out and more or less hang the system.  
The problem can be eliminated by calling the routines in this 
order:  KEYSTAT, BELL, WAIT.  It involves changing 13E9h to Call 
437BH, and 13ECH to Call 0E53H.
   
I hope you can change these lines in version 2.  MEX is a great 
program, and I thank you very much.  When I have the my SANYO 
overlay spruced up I'll upload it.
