RS-232C Parameters
Hardware Handshaking
When Option 2 is selected, RTS is always high or low (user-programmed logic
level). However, the base waits for CTS to be asserted before transmitting data.
If CTS is not asserted within two seconds (default), the base issues an error
indication and discards the data.
RTS/CTS OPTION 2
When Option 3 is selected, the base asserts RTS prior to any data transmission,
regardless of the state of CTS. The base waits up to two seconds (default) for
CTS to be asserted. If CTS is not asserted during this time, the base issues an
error indication and discards the data. The base deasserts RTS when
transmission is complete.
RTS/CTS OPTION 3
