Plug & Play would most likely help you detect the problem. 'If' it is an IRQ problem it will be most likely because 2 Comm ports are either trying to share the same IRQs or addresses. I would suspect IRQs. Remember if a mouse is on com1 then com3 cannot be used. Same as if it were on com2 then com4 can not be used.

See if there is an internal modem or some other device & check the settings.

Win 95 will usually flag you if a conflict occurs soo -- I dunno...
