Q – Quiet
The command enables or disables the sending of result codes to the DTE according to the
parameter supplied.The parameter value, if valid, is written to S14 bit 2.
Syntax:
ATQ
= 0
Quiet mode OFF (default)
= 1
Quiet mode ON
Examples:
Result Codes:
OK
ERROR
Otherwise
&Q – Async Mode
This command is used to control the connection modes permitted. It is used in conjunction
with S36 and S48. (Also, see \N).
&Q0 Selects direct asynchronous operation.The value 000b is written to S27 bits 3, 1,
and 0, respectively.
&Q5 The modem will try to negotiate an error-corrected link.The modem can be config-
ured using S36 to determine whether a failure will result in the modem returning
on hook or will result in fallback to an asynchronous connection.The value 101b
is written to S27 bits 3, 1 and 0 respectively (Default).
&Q6 Selects asynchronous operation in normal mode (speed buffering).The value 110b
is written to S27 bits 3, 1 and 0, respectively.
%Q – Report Line Signal Quality
Reports the line signal quality. Returns the higher order byte of the EQM value. Based on the
EQM value, retrain or fallback/fall forward may be initiated if enabled by %E1 or %E2.
S – S-Register
Syntax:
ATS

&S – DSR Override
This command selects how the modem will control DSR.The parameter value, if valid,
is written to S21 bit 6.
&S0 DSR will remain ON at all times. (Default)
&S1 DSR will become active after answer tone has been detected and inactive
after the carrier has been lost.
