Auxiliary RS232 interface

The auxiliary serial interface is used exclusively for RS232 point to point
connections.
The parameters relative to the auxiliary interface (baud rate, data bits, etc.)
as well as particular operating modes such as local echo can be defined
using the WINHOST utility program or Host Mode programming. For more
details refer to paragraph 2.9 and to the section "Auxiliary Interface Menu" in
the WINHOST Help On Line.
The following pins of the 25-pin connector are used to connect the RS232
auxiliary interface:
The RTSAUX and CTSAUX signals control data transmission and
synchronize the connected devices. If the RTS/CTS handshaking protocol is
enabled, the DS41 activates the RTSAUX output to indicate a message is to
be transmitted. The receiving unit activates the CTSAUX input to enable the
transmission.
