<SNIP> Every PCI internal modem I'd had was always configured by default to be on Com3 (unless there was the means to set it to whatever COM via jumpers [I had such a modem]). I wonder if I was just "lucky" that they were all set to COM3.
The other thing is that in the BIOS there ought to be a setting - which I have always wondered about as to why it's there - where you assign the IRQ to the modem.
Cheers.
Most motherboards have two serial ports, com1 and com2 or ttyS0 and ttyS1. Your modem gets set to com3 because that is the next in line after the two on the motherboard. In the days of serial mice I would have to set my BIOS to make my on board ports com1 and com3. This way my modem would become com2 and no matter which port I plugged my mouse into, there would not be an IRQ conflict. Not a big problem anymore as most people are not even using the serial ports on the motherboard. Ports and IRQs for these ports are generally like this: DOS LINUX PORT IRQ ----------------------------------------- com1 ttyS0 0x3f8 4 com2 ttyS1 0x2f8 3 com3 ttyS2 0x3e8 4 com4 ttyS3 0x2e8 3 HTH Louis
