I need to use the serial port on the IBM serial/parallel board to access an RS422 device. I know this can be done because I have some software that does it. Unfortunately, I only have the executable and I need some source code to understand how it's done. I'm really interested in doing this under 4.3 Unix on an RT, but programming the board's registers is the same under any os.... I'm really stuck on this, so any help would be greatly appreciated.
