WIN 95 CANNOT INSTALL MODEM

I JUST DUAL BOOTED ONE OF MY W/S WITH NT W/S
& WIN95.WITH WIN NT I DID NOT ENCOUNTER ANY PROBLEM WITH INSTALLING MY MODEM.TO SUM UP THAT SEQUENCE ALL THAT WAS NECESSARY WAS TO ADD A PORT (COM3,I/O 2E8 & DEFAULT IRQ).WITH
WIN95 I AM UNABLE TO INSTALL THE MODEM.COM 1 &2 TELLS ME THE PORTS ARE OPEN SO THAT RESOURSE IS TAKEN.WITH ADD NEW HARDWARE IT TOLD ME OF AVAILABLE PORT .COM 3,INSTALLED IT THERE,NOTIFIED ME IT WAS SUCCESSFULLY INSTALLED BUT WHEN I DIAL OUT IT GIVES ME THE PORT IS OPEN,SWITCHING IT TO COM 2 GIVES ME A HARDWARE FAILURE.ANY THOUGHTS WILL BE APP.—–THANX–
