Other RTS/CTS Options

The following options offer alternatives to Standard RTS/CTS Handshaking.
• RTS/CTS Option 1: The scanner asserts RTS before transmitting and ignores the
state of CTS. The scanner deasserts RTS when the transmission is complete.
• RTS/CTS Option 2: 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 two seconds, the scanner issues an error beep and discards
the data.
• RTS/CTS Option 3: The scanner asserts RTS before transmitting, regardless of
the state of CTS. The scanner waits up to two seconds for CTS to be asserted. If
CTS is not asserted during this time, the scanner issues an error beep and discards
the data. The scanner deasserts RTS when transmission is complete.
• RTS/CTS PC: Standard RTS/CTS hardware handshaking used by the PC. The
host can deassert CTS to prevent the scanner from transmitting, and the scanner
can deassert RTS to prevent the host from transmitting.
