- Oddly enough, switching the mouse and modem COM port assignments can
- do wonders. You'll have to remove the SERIAL=COM2 parameter from your
- mouse device driver (in CONFIG.SYS).
-
- Why? COM2 uses a lower interrupt number, meaning it gets serviced
- first, before the mouse, if both need servicing at the same time.

- Are you using hardware handshaking (is it enabled in the modem)? Do
- you have a CALL=...MODE line in your CONFIG.SYS to set BUFFER=AUTO and
- RTS=HS?

- Make sure you are using the latest CommPak DLL -- it is available from
- ftp-os2.nmsu.edu via anonymous ftp as filename cpk2_102.zoo.
