The configuration you mention: MOUSE COM1, MODEM COM3 will usually have an
IRQ conflict since both would use IRQ4. Problems would tend to show up when
communicating with the modem (message or data transfer in progress) and the
mouse is moved. Usually the conflict is discovered at boot up by WIN95.

One configuration I presently use is Mouse on COM1 and MODEM on COM4 since
my particular modem had a problem with COM2. I have changed modems in that
slot three times (upgrading to higher speeds), and kept the COM4 setting
without problems.
