- 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
