This is all explained very clearly in the *.txt files that come with Windows
3.0.  The mouse must be on COM1 or COM2.  The modem can be at COM3, there's a
bunch of parameters that have to be setup in either system.ini or win.ini, I
can't remember which.  I have my mouse on COM1, LapLink on COM2, and Modem on
COM3 and have had no problems with this setup, in or out of Windows 3.0.
