Table H-4. Smartmodem 2400/2400B Command Set (Continued)
Command
&R0 Track CTS according to RTS.
Ignore RTS; always assume presence of CTS.
&R1
In the default state (&RI), CTS is forced on. In &R1, CTS follows RTS with
the value specified in register S26.
Assume presence of DSR signal.
&S0
Track presence of DSR signal.
&S1
In the default state, DSR remains high when the modem is on. In the
alternate state, an off-to-on transition occurs after the answer tone is
received (treating the modem as a "dumb" modem". This command is a
CCITT V.22 recommendation.
&T0 Terminate test in progress.
Initiate local analog loop back.
&T1
Initiate digital loop back.
&T3
Grant request from remote modem for RDL.
&T4
Deny request from remote modem for RDL.
&T5
Initiate remote digital loop back.
&T6
Initiate remote digital loop back with self-test.
&T7
Initiate local analog loop back with self-test.
&T8
This set of commands provides a test suite of the local and remote
connection.
&V View active configuration, user-defined profiles, and stored numbers.
This command allows viewing of the information stored in the modem's
EEPROM.
&W0 Save storable parameters of active configuration as user profile 0.
Save storable parameters of active configuration as user profile 1.
&W1
The modem permits two active configurations, each of which can be stored
in the EEPROM for future use.
&X0 Modem provides transmit clock signal.
Data terminal provides transmit clock signal.
&X1
Receive carrier provides transmit clock signal.
&X2
This command set provides flexibility for clock source signal in synchronous
communications.
Recall user profile 0 on power-up.
&Y0
Recall user profile 1 on power-up.
&Y1
Either of the two stored two user profiles can be selected as the default for
future communication sessions.
