Hi -
   I'm looking for a COM (serial port) driver that installs without
using an interrupt.  That is, it only supports polled operation.

All I really need to do is to read and set a few of the RS-232
status lines every now in then - no data i/o at all.  

I'd like to use such a driver on, say, COM4 that would normally
be unusable because it shares an interrupt with COM2.

Alternatively, does anyone have an (electronic) reference to 
programming the AT's UART?  If I can't find a driver, I could always
access the hardware directly (as a last resort).

Any pointers, etc. would be appreciated.

Thanks!
Bill
