RTS
Note:
Effective only in synchronous mode. This setting is ignored in asyn-
chronous mode. RTS is always used as a hardware flow control sig-
nal in this case.

The modem assumes that RTS is always ON
AT&R1
and ignores the serial port signals. (Default)
Delay before CTS responds to RTS's change.
AT&R0
The delay is set in S26.
The modem forces DSR to always remain ON.
AT&S0
(Default)
According to ITU-T. DSR ON during handshake.
AT&S1
If S41.5=1, DSR follows CD, and pulses off for
0.5 sec for CD on-off transition. If S44.4=1,
DSR follows DTR.
The modem echoes commands. (Default)
ATE1
The modem does not echo commands.
ATE0
The modem returns result codes. (Default)
ATQ0
The modem does not return result codes.
ATQ1
If S40.1=1, the modem does not return result
ATQ2
codes in answer mode.
Selects DTE port asynchronous serial speed. AT
command auto speed detection will override
this selection.
