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 2 seconds (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 2 seconds (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.
