AT Commands
Page 44
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),
e.g., AT&Q6. To terminate the test in progress, the escape sequence must be entered
first.
Syntax &T[<value>]
Defined Values
<value> Decimal number corresponding to the selected option.
0 Terminates test in progress. Clears S16.
1 Initiates local analog loopback, V.54 Loop 3. Sets S16
bit 0. 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.
&Y - Designate a Default Reset Profile
This command selects which user profile will be used after a hard reset.
Syntax &Y<value
Defined Values
<value> Decimal number corresponding to the selected profile.
0 The modem will use profile 0.
1 The modem will use profile 1.
Result Codes
OK <value> = 0 to 1.
ERROR If <value> > 1, or if NVRAM is not installed or is not
operational.
&W - Store Current Configuration
Saves the current (active) configuration (profile), including S-Parameters, in one of the
two user profiles in NVRAM as denoted by the parameter value. This command will
yield an ERROR message if the NVRAM is not installed or is not operational as
detected by the NVRAM test.
The current configuration is comprised of 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 (see &Yn command).
Syntax &W<value>
Defined Values
<value> Decimal number corresponding to the selected profile.
0 Store the current configuration as profile 0.
1 Store the current configuration as profile 1.
Result Codes
OK <value> = 0 to 1.
ERROR Otherwise.
&Zn=x - Store Telephone Number
The modem can store up to four telephone numbers and each telephone number dial
string can contain up to 31 digits. (Requires 256-byte NVRAM installed.)
