[Ham-Computers] Lack of com ports problem

[Dgb]

I would re-enable com2 in the bios,  change the modem's jumper
back to use com4 and let it use irq3 if it wants to. Then go into
system properties, device manager, double click on com2, then
click on the resources tab. There you unclick the "Use automatic
setting" box and then you can change com2's irq to something
else, and if you pick an irq used by something else it will tell
you at the moment if there are any conflicts.

Other wise they do make y-cables for a keyboard and mouse to
share the same plug.

Good luck ... 73 Dwight W9YQ
