Hardware Handshaking (Continued)

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 two seconds (default), the scanner issues an error indication and discards the
data.
When Option 3 is selected, the scanner asserts RTS prior to any data transmission, regardless
of the state of CTS. The scanner waits up to two seconds (default) for CTS to be asserted. If
CTS is not asserted during this time, the scanner issues an error indication and discards the
data. The scanner deasserts RTS when transmission is complete.

Software Handshaking

This parameter offers control of the data transmission process in addition to, or instead of,
that offered by hardware handshaking. There are five options.
If Software Handshaking and Hardware Handshaking are both enabled, Hardware
Handshaking takes precedence.
None
When this option is selected, data is transmitted immediately.
