RTS/CTS Option 1
When RTS/CTS Option 1 is selected, the scanner asserts RTS before transmitting and ignores the state of CTS.
The scanner de-asserts RTS when the transmission is complete.
RTS/CTS Option 2
When Option 2 is selected, RTS is always high or low (user-programmed logic level). However, the scanner waits
for CTS to be asserted before transmitting data. If CTS is not asserted within Host Serial Response Time-out
(default), the scanner issues an error indication and discards the data.
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.
