Are you sure the mice are serial mice?
Most new mice no longer support serial port connections even with an adapter.
If the mouse does support serial port mode, make sure that you have the correct adapter.
Next, are the COMM ports enabled in BIOS settings, and do they show up in Device Manager?

This sounds like an older BIOS that is Plug and Play 1.0 compliant.
In this case you have to set COM1 to IRQ 4 and the I/O to 03F8.
There were several bugs in PnP 1.0
In severe cases, you will have to manually force IRQ4 to ISA. (Also in the BIOS)
