Command Reference
Data Command Set - 21
5 Selects MNP error-correction mode and forces &Q5 (the modem
will try to negotiate an error corrected link). Failure to make an
MNP error-correction connection results in the modem hanging
up.
Result Codes
OK <mode> = 0 to 5.
ERROR Otherwise.
&F - Set to Factory-Defined Configuration
This command instructs the modem to set all parameters to factory default values
defined in the product Configuration Table
The modem loads the factory default configuration (profile). The factory defaults
are identified for each command and in the S-Parameter descriptions. A
configuration (profile) consists of a subset of S-Parameters.
Syntax
&F
Result Code
OK
&T - Local Analog Loopback Test
The modem will perform the local analog loopback test if &T1 is selected. The test
can be run only when in an asynchronous operation in non-error-correction mode
(normal). To terminate the test in progress, the escape sequence must be entered
first. If S18 is non-zero, the test will terminate automatically after the time
specified by S18 and the OK result code will be reported.
Syntax
&T[<value>]
Defined Values
<value> Decimal number corresponding to the selected value.
0 Terminates test in progress.
1 Initiates local analog loopback, V.54 Loop 3. If a connection exists
when this command is issued, the modem hangs up. The
CONNECT XXXX message is displayed upon the start of the test.
I - Request Identification Information
