I have a four port ASYNC/AT communications card for 
the ibm PC,XT,AT and compatibles (made by AST research).
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
