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 1
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.
