Parameter Description
RTS/CTS Loop, No Description RTS and CTS are looped, so that CTS echoes the state of RTS, but RTS
does not control the ON/OFF state of the carrier.
Loop, RTS Controls Tx Out
RTS and CTS are looped, so that CTS echoes the state of RTS, and RTS
controls the ON/OFF state of the carrier (in other words, the modem will not
bring up its TX carrier until RTS is asserted).
Ignore RTS, Assert CTS RTS is ignored and CTS is asserted unconditionally.
N/A - 1:N system in use
If the 1:N switch on the rear panel is active, then RTS/CTS are not supported;
the pins are assigned to redundancy functions.
