This command causes the modem to switch from on line command mode
to on line data mode. If the modem is in off line command mode, you will
receive the message ERROR. With the parameter 1 a retrain is performed
before the modem switches back to on line data mode.
ATQ
Response on/off (Quiet)
This command determines whether or not the result codes are sent to the
terminal.
0 -
Result code on (default)
1 -
Result code off
AT%Q
Line signal quality
This command is used to monitor line quality. Values between 000 and
016 correspond to a good line quality. Values between 017 and 127
indicate poor quality. The line is monitored constantly when the modem is
on line. When command AT%E1 is activated and the signal value is higher
than 016, a retrain is carried out.
AT&Q Synchronous/asynchronous
mode
This command is an extension of the command &M which is used in
combination with registers S36 and S48 to monitor the permitted
connection modes.

5 -
The modem tries to establish a connection with error
correction. With S36, the modem can be configured in such a
way that an error causes it to be switched off line or to return to
a normal asynchronous connection (default).
6 -
The modem operates in normal asynchronous mode.
See AT\N.
AT&R RTS/CTS
control
This command controls CTS in on line synchronous mode. The operation
of CTS is adjusted with hardware flow control.
0 -
RTS to CTS is delayed according to the setting of register S26.
