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.
