The drivers that caused the modem overrun was:
IBM1S506.zip ³   106462³11/15/98³16:02
ibmidecd.zip ³    40833³11/15/98³16:06
OS2DASD.ZIP  ³    63182³11/15/98³16:10

The ones I use that don't have the over run problem are:
IBM1S506.ADD ³    30636³10/30/95³15:13
OS2DASD.DMD  ³    34228³10/30/95³14:44
IBMIDECD.FLT ³    20490³ 1/10/95³20:47

This are from FP 17.

I'm pretty sure it was just the IBM1S506.ADD driver that caused the problem. 
IIRC, I only installed the IBM1s506 driver at first, and did the OS2DASD.DMD
file later, in an attempt to fix the problem.  I could put in the drivers,
modem overruns, take them out, no overruns.
