Single Line Connect Message Enable
Enables or disables the single-line connect message format as follows:
None
\V
0
Connect messages are controlled by the command settings X, W,
and S95.
\V
1
Connect messages are displayed in the single line format described
below subject to the command settings V (Verbose) and Q (Quiet). In
Non-Verbose mode (V0), single line connect messages are disabled
and a single numeric result code is generated for CONNECT DTE.
When single line connect messages are enabled, there are no CARRIER,
PROTOCOL (+ER:), or COMPRESSION (+DR:) messages apart from the
fields described below.
The single line connect message format is:
CONNECT <DTE
Speed>/<Modulation>/<Protocol>/<Compression>/<Line Speed>
Where:
DTE Speed =
DTE speed, e.g., 57600.
Modulation =
"V90" for V.90 modulation.
"K56" for 56K modulation.
"V34" for V.34 modulation.
"V32" for V.32 or V.32bis modulation.
Note:
Protocol =
"NONE" for no protocol.
"ALT" for Microcom Network Protocol.
"LAPM" for LAP-M protocol.
Compression =
"V44" for V.44 compression.
"V42B" for V.42bis compression.
"ALT" for Microcom MNP5 compression.
Note:
Line Speed =
Asymmetric rates are displayed as "/rate:TX/rate:RX",
e.g., /1200 TX/75 RX.
Symmetric rates are displayed as a single DCE rate,
e.g., 14400.
Report Line Signal Level
Returns a value, which indicates the received signal level. The value
returned is a direct indication (DAA dependent) of the receive level at the
MDP, not at the telephone line connector. For example, 009 = -9 dBm, 043
= -43 dBm, and so on.
OK
Report Line Signal Quality
Reports the line signal quality (DAA dependent). 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.
AT%Q
015
OK
If connected.
ERROR
If not connected, or connected in 300 bps, V.23, or fax modes.
"V92" for V.92 modulation.
Modulation is omitted for all other modulations.
Compression is omitted if protocol is NONE.
