74 Chapter 8 Special Features: Modem Emulation
AT&Rn
RTS/CTS Option
This selects how the Digi device controls CTS. CTS is modified if hardware
flow control is selected (see &K command). The parameter value, if valid, is
written to S21 bit2.
&R0CTS reflects the ability of the modem to transmit data. For example,
CTS will drop during retrains. In sync mode, CTS tracks the state of RTS;
the RTS-to-CTS delay is defined by S26. In async mode, CTS is normally
ON and will turn OFF only if required by flow control.
&R1CTS forced on (default). In sync mode, CTS is always ON (RTS
transitions are ignored). tracks the state of RTS. In async mode, CTS is
normally ON and will turn OFF only if required by flow control.
&R2CTS follows RTS.

AT&Sn
DSR Override
This command selects how the modem will control DSR. The parameter
value, if valid, is written to S21 bit 6.
&S0DSR will remain ON at all times. (Default.)
&S1DSR will become active after answer tone has been detected and
inactive after the carrier has been lost.
