2.4.3 Auxiliary RS232 Interface
The auxiliary serial interface is used exclusively for RS232 point to point
connections.
The parameters relative to the aux interface (baud rate, data bits, etc.) as
well as particular operating modes such as LOCAL ECHO can be defined
using the WinHost utility program installed from the diskette or "Host Mode"
programming provided on diskette.
The following pins of the 25-pin connector are used to connect the RS232
auxiliary interface:
