Having RS232 or 422 shouldn't cause any difference to software as you're 
using asynchronous communication (i.e. without any flow control and 
handshaking synchronisation lines). Most RS422 devices I've seen need 
only Tx & Rx line pairs. The same program should work fine for both 
RS232 and RS422.
