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.
