The option is changed using the
ENTER. The following options are possible :
1) RTS/CTS Loop, No Action
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.
2) 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).
3) Ignore RTS, Assert CTS
RTS is ignored, and CTS is asserted unconditionally.
4) N/A - 1:N system in use -
