The card is just four ports (NS16450's) using an RS-232 interface to handle asynchronous data transmission between pc and serial devices. What I am looking for is a driver for this (or a similar) card preferably written in C. Also in the event of having to write one myself if anyone has a sample C program that does the required setting up and trapping of a hardware interupt on the ibm ps/xt/at this would be most valuable. I have a microsoft C compiler. Thanks. doug@wapsyvax.oz
