Either RS-232 or RS-485 ports can be used in point-to-point mode.
Each port can be configured for input or output data by making DOS
calls. To transfer files, a Kermit server can be invoked by selecting
option "3) COM" in the user command menu or by typing "COM" in
the Ready prompt and a Kermit utility should also be run on the
Host side in order to complete the data connection.
