Most X25 implementations use a 'PAD', a device that maintains the X25
connection and converts the data into/from RS-232. There are also PC boards
which do the same thing. In the X25 implementations I've worked on, this is always how it is done. Once the PAD is in place, you just send/receive data from the MSCOMM control like any other RS-232 connection.
