3 Selects auto reliable mode. This operates the same as \N2 except failure to make a
reliable connection results in the modem falling back to the speed buffered normal
mode. (Forces &Q5, S36=7, and S48=7.)
4 Selects LAPM error-correction mode. Failure to make an LAPM error-correction
connection results in the modem hanging up. (Forces &Q5 and S48=0.) Note: The -
K1 command can override the \N4 command.
5 Selects MNP error-correction mode. Failure to make an MNP error-correction
connection results in the modem hanging up. (Forces &Q5, S36=4, and S48=128.)
Result Codes
OK n = 0 to 5.
ERROR Otherwise.
10.6.4 \Vn - Single Line Connect Message Enable
This command enables or disables the single line connect message format as follows:
Command: \Vn
n Decimal number corresponding to the selected option.
0 Connect messages are controlled by the command settings X, W, and S95.
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>/<Voice and Data>
where:
<DTE Speed> = DTE speed, e.g., 57600.
Modulation = “V90” for V.90 modulation.
“K56” for K56flex modulation.
“V34” for V.34 modulation.
“V32” for V.32 or V.32bis modulation.
NOTE: Modulation is omitted for all other modulations.
Protocol = “NONE” for no protocol.
“ALT” for Microcom Network Protocol.
“LAPM” for LAP-M protocol.
Compression = “ALT” for Microcom MNP5 compression.
“V42B” for V.42bis compression.
