ERROR If the modem is connected.
10.3.4 &Gn - Select Guard Tone
This command causes the modem to generate the guard tone selected by this command (DPSK
modulation modes only).
The parameter value, if valid, is written to S23 bits 6 and 7.
&G0 Disables guard tone. (Default)
&G1 Disables guard tone.
&G2 Selects 1800 Hz guard tone. This command may not be permitted in some countries.
Result Codes:
OK n = 0 to 2.
ERROR Otherwise.
10.3.5 &Kn - Flow Control
This command defines the DTE/DCE (terminal/modem) flow control mechanism. The parameter
value, if valid, is written to S39 bits 0, 1, and 2.
&K0 Disables flow control.
&K3 Enables RTS/CTS flow control. (Default for data modem modes.)
&K4 Enables XON/XOFF flow control.
&K5 Enables transparent XON/XOFF flow control.
Result Codes:
OK n = 0, 3, 4 or 5.
ERROR Otherwise.
10.3.6 &Ln - Leased Line Operation
This command requests leased line or dial-up operation. This command is provided for compatibility
only; no mode change is performed, dial-up operation continues. The OK response is returned for a
valid parameter, but no other action is performed. The parameter value, if valid, is written to S27 bit
2.
&L0 Requests dial-up operation. Dial-up operation continues.
Result Codes:
OK n = 0.
ERROR Otherwise.
10.3.7 &Mn - Asynchronous/Synchronous Mode Selection
This command determines the DTR operating mode. The modem treats the &M command as a
subset of the &Q command.
