RS-232 Interface
RTS/CTS Option 3
When Option 3 is selected, the scanner asserts RTS prior to any data transmission,
regardless of the state of CTS. The scanner waits up to Host Serial Response Time-out
(default) for CTS to be asserted. If CTS is not asserted during this time, the scanner issues
an error indication and discards the data. The scanner de-asserts RTS when transmission
is complete.
RTS/CTS Option 3

If Software Handshaking and Hardware Handshaking are both enabled, Hardware
Handshaking takes precedence.
