That's not correct. I'm writing this on a Win95 PC with 4 com ports. COM3
has IRQ11 and
COM4 IRQ12 - I'm using a 2port 16550 ISA serial card. (IRQ 12 is normally
PS2 Mouse interrupt - unused on my PC).
For more than two extra ports, get a custom 4 or eight port card and driver
- usually shares a single
interrupt but card is more $.

Works fine all 4 ports at once. Trick I think is to "fool" Win95 by adding
6 comports - you can
change IRQ of COM5 and COm6 to 11 or 12 or whatever. Then delete ports 3
and 4 and reboot.
Easy.
