	i have been working on a program to read and write com ports 3 & 4

	i can get com 1 & 2 to work but i can't seem to make 3 & 4 work

	i get the addresses out of the bios data area and they seem right 

	cause i can write to the ports and they react but i think the interupts

	are screwy...

					can anyone help here ?

						thanks in advance,
								iain.
