AT&V Display Current Configuration and Stored Profile
Reports the current (active) configuration, the stored (user)
profiles, and the four stored telephone numbers. The stored profiles
and telephone numbers are not displayed if the NVERAM is not installed
or is not operational as detected by the NVRAM test during reset
processing.
AT&Wn Store Current Configuration
AT&W0 Store the current configuration as profile 0.
AT&W1 Store the current configuration as profile 1.
AT&Yn Designate a Default Reset Profile
Selects which user profile will be used after a hardware reset.
AT&Y0 The modem will use profile 0.
AT&Y1 The modem will use profile 1.
AT&Zn Store Telephone Numbers
The modem can store up to four telephone numbers and each telephone
number dial string can contain up to 45 digits.
AT&Zn=x n=0 to 3 and x=dial string.
AT%En Enable/Disable Line Quality Monitor And
Auto-Retrain or Fallback/Fall Forward
Controls whether or not the modem will automatically monitor the line
quality and request a retrain (%E1) or fall back when line quality
is insufficient or fall forward when line quality is sufficient (%E2).
Applies to dial-up line only. The parameter value, if valid, is
written to S41 bits 2 and 6. If enabled, the modem attempts to retrain
for a maximum of 30 seconds.
AT%E0 Disable line quality monitor and auto-retrain.
AT%E1 Enable line quality monitor and auto-retrain.
AT%E2 Enable line quality monitor and fallback/fall forward.(Default)
AT%L 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=-9dBm, 043=-43 dBm, and so on.
AT%Q 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\Gn Modem-to-Modem Flow Control (XON/OFF)
In non-error correction mode, the modem enables or disables the
generation or recognition of modem-to-modem XON/XOFF flow control
according to the parameter supplied. The parameter value, if valid,
is written to S41 bit 3. In error correction mode, the setting of
modem-to-modem XON/XOFF flow control is ignored. However, the serial
port flow control settings(AT&K) remain active during a reliable
link. Due to the buffering system used in the modem, modem-to-modem
flow control is normally disabled.
