Standard RTS/CTS：Scan the bar code below to select Standard RTS/CTS
Hardware Handshaking.
Standard RTS/CTS
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 Host Serial
Response Time-out, the scanner issues an error indication and discards the
data
RTS/CTS Option 2
