Qn – Quiet Results Codes Control
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.
Q0 Enables result codes to the DTE. (
Default
)
Q1 Disables result codes to the DTE.
%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.
&Sn – 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.
%Un – Select µ-Law or A-Law Codec Type
This command selects µ-Law or A-Law codec type for V.90 and K56flex modulation.
This command also stores the selected setting directly to NVRAM.
%U0 Selects µ-Law.
%U1 Selects A-Law.
Vn – Result Code Form
This command selects the sending of short-form or long-form result codes to the DTE.
The parameter, if valid, is written to S14 bit 3.
V0 Enables short-form (terse) result codes. Line feed is not issued before a short-form
result code.
V1 Enables long-form (verbose) result codes. (
Default
)
&Q – Async Mode
This command is used to control the connection modes permitted. It is used in conjunc-
tion 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. See &M0.
&Q5 The modem will try to negotiate an error-corrected link. The modem can be con-
figured using S36 to determine whether a failure will result in the modem return-
ing 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.
