Software Handshaking - Symbol LS1900 Series Product Reference Manual

Programming the Scanner
RTS/CTS Option 3
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 2 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.
RTS/CTS Option 3

that offered by hardware handshaking. There are five options.
If Software Handshaking and Hardware Handshaking are both enabled, Hardware
Handshaking takes precedence.
None
