Handshaking Control

The data interface consists of an RS-232 port designed to operate either with or without
the hardware handshaking lines, Request to Send (RTS), and Clear to Send (CTS). Hand-
shaking Control includes the following options:

RTS — RTS is asserted during transmissions. CTS is ignored.

RTS/CTS — RTS is asserted during transmissions. CTS gates transmissions.

RTS/XON/XOFF — RTS is asserted during transmissions. CTS is ignored. XON and
XOFF gate transmissions.

RTS On/CTS — RTS is always asserted. CTS gates transmissions.

RTS/CTS Scan Control — RTS is asserted during transmissions. CTS gates transmis-
sions and controls enable and disable state of scanner.
