Ben,

What driver are you using for the modem serial line and does the modem
share IRQ 10 with any other device? I had a problem getting my modem to
work about 2 years ago, after I got a new system. Steven Levine was kind
enough to point out that some versions of COM.SYS do not like to share
IRQ's. I updated to a newer version of IBM's COM.SYS and that did the
trick. I believe you can also use Ray Gwinn's SIO.SYS.
