Function
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.
RTS and C TS ar e l ooped s o t hat C TS echoes t he s tate of R TS, and R TS
controls the ON/OFF state of the carrier (i.e., the modem will not bring up its TX
carrier until RTS is asserted).
RTS is ignored and CTS is asserted unconditionally.
