All of my technical documentation on the pc and at predated com3 and com4, but I now need to make my software work with them. Does anybody know the interrupt number and (base) port address for com3 and com4 on the pc/xt/at ? Thanks in advance, kmt

According to Appendix D of my ProComm 2.4.2 manual: COM3 has a base port address of 3E8h and interrupts at IRQ4. COM4 has a base port address of 2E8h and interrupts at IRQ3. -- Rich Wales // UCLA Computer Science Department // +1 (213) 825-5683 3531 Boelter Hall // Los Angeles, California 90024-1596 // USA wales@CS.UCLA.EDU ...!(ucbvax,rutgers)!ucla-cs!wales "Sir, there is a multilegged creature crawling on your shoulder."
