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). Handshaking
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 transmissions
and controls enable and disable state of scanner.
