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
LDHOST utility program or "Host Mode" programming provided on diskette.
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 scanner
activates the RTSAUX output to indicate a message is to be transmitted. The
receiving unit activates the CTSAUX input to enable the transmission.
