&Tn Self-test commands
These tests can help to isolate problems if you experience periodic data
loss or random errors.
&V Display Current Configuration
This command displays the current configuration of the modem. If
nonvolatile memory is supported the stored profiles are displayed as well.
&W Store current configuration
Saves the current (active) configuration (profile), including S-Registers.
The current configuration comprises a list of storable parameters illustrated
in the &V command. These settings are restored to the active configuration
upon receiving a Zn command or at power up. Refer to the &V command.
&Zn=x Store telephone number
This command is used to store up to four dialing strings in the modem's
nonvolatile memory for later dialing. The format for the command is
&Zn="stored number" where n is the location 0-3 to which the number
should be written. The dial string may contain up to 34 characters. The
ATDS=n command dials using the string stored in location n.
\Nn Error control mode selection
This command determines the type of error control used by the modem
when sending or receiving data.
