RS232 Handshaking

RS232 Handshaking allows control of data transmission from the scanner
using software commands from the host device. When RTS/CTS is
turned Off, no data flow control is used.
Flow Control, No Timeout: The scanner asserts RTS when it has data to
send, and will wait indefinitely for CTS to be asserted by the host.
Two-Direction Flow Control: The scanner asserts RTS when it is OK for
the host to transmit. The host asserts CTS when it is OK for the device to
transmit.
Flow Control with Timeout: The scanner asserts RTS when it has data
to send and waits for a delay (see RS232 Timeout on page 2-28) for CTS to
be asserted by the host. If the delay time expires and CTS is not asserted,
the device transmit buffer is cleared and scanning may resume.
Default = RTS/CTS Off.
