When the CTS line (RTS signal of the host) is turned OFF while sending a TxD signal,
the scanner transmits one character and waits. When the CTS signal is turned ON while
transmitting a character, the character will be transmitted.

After data has been transmitted, the scanner expects to receive one of the
following responses from the host:
ACK response—Action: The scanner completes transmission with the good-
read buzzer and returns to the initial state.
NAK response—Action: The scanner sends the data again and waits for the
response from the host.
DC1 response—Action: The scanner returns to waiting for the trigger, if it has
a trigger (the initial state).
None response—Action: The scanner sounds the error buzzer and returns to
the initial state.
