I would look at setting a lower MTU/MRU, 576 tends to be good, or
alternatively look at what comm driver (comm.drv) is being used by
win3.1 as the one that shipped was pretty cr*p and tended to result in a
lot of comm errors even with 16550 uarts. There are various 'enhanced'
ones around
I see Sherwood has suggested 3.02 of IEAK this may also help, also
turning off modem compression may help.
Best thing is try it and see. We have quite a few people using IEAK 3.02
on WIn 3.1x with little or no problems dialing into our PM3.
btw did your customer get anywhere, or knowware ;-) with the
DMS-100/PM3 problem ????
Cheers
Phil
