Hardware Handshaking (continued)
• None: Scan this bar code to disable hardware handshaking.
• Standard RTS/CTS: Scan this bar code to select Standard RTS/CTS Hardware Handshaking.
• RTS/CTS Option 1: If you select RTS/CTS Option 1, the digital scanner asserts RTS before transmitting and
ignores the state of CTS. The digital scanner de-asserts RTS when the transmission completes.
• RTS/CTS Option 2: If you select Option 2, RTS is always high or low (user-programmed logic level).
However, the digital scanner waits for CTS to be asserted before transmitting data. If CTS is not asserted
within Host Serial Response Time-out (default), the digital scanner issues an error in dication and discards
the data.
• RTS/CTS Option 3: If you select Option 3, the digital scanner asserts RTS prior to any data transmission,
regardless of the state of CTS. The digital scanner waits up to Host Serial Response Time-out (defaul t) for
CTS to be asserted. If CTS is not asserted during this time, the digital scanner issues an error indication and
discards the data. The digital scanner de-asserts RTS when transmission is comp lete.
