&Rn  RTS Action Request-to-Send (RTS) is a signal from the DTE to the modem indicating the DTE has data to send to the modem.

&R0 Standard EIA-232. DTE controls RTS to the modem in normal EIA-232-D operation. RTS must be ON for the DTE to transmit to the modem.

&R1 Ignores RTS. Modem assumes RTS is always ON. Use this selection when the DTE does not provide RTS to the modem.

&R2 Simulated Control Carrier. RTS input controls the remote modem's LSD signal. This is used for DTEs that require Line Signal Detect (LSD) to toggle ON and Off to simulate half-duplex operation.
