Command Description
AT-TTE=U1,
U2,
U3
Parameter Configuration for Priority Circuit
The command AT-TTE=U1, U2, U3 will set the change of the loop voltage. The set-
tings are required to detect AT-STE=<n> .
(see Chap. 5.10)
U1 Line busy
Default factory setting: u1=1000 (10V)
U2 Going off-hook on account of a telephone connected in series
Default factory setting: u2=100 (1V)
U3 Remote terminal connection abort
Default factory setting: u3=500 (5V)
Note: These settings cannot be stored with
AT&W
in the power fail-safe
memory.
AT*U<n> Select the data format at the serial interface
The data format can be preselected with this command. This will, however, not switch
off the automatic detection. As soon as an
AT is recognized, the serial interface will set
itself to the recognized speed and protocol.
If no AT is sent, the selected protocol is maintained until a hardware reset is per-
formed. If the selected protocol should be maintained longer, it must be stored with
AT&W.
Attention: This command will not change the registry S23! It only changes if the
automatic speed and protocol detection is used.
AT*U0 8 data bits, no parity, 1 stop bit
AT*U1 7 data bits, odd parity, 1 stop bit
AT*U2 7 data bits, even parity, 1 stop bit
AT*U3 7 data bits, no parity, 1 stop bit
AT*U4 7 data bits, odd parity, 2 stop bits
AT*U5 7 data bits, even parity, 2 stop bits
AT*U6 7 data bits, no parity, 2 stop bits
AT*U7 8 data bits, odd parity, 1 stop bit
AT*U8 8 data bits, even parity, 1 stop bit
AT*U9 8 data bits, no parity, 2 stop bits
ATV<n> Format of modem messages
This command determines if the modem transmits messages to the application in
short or long format.
ATV0 Messages in short format, i.e. only the error number
ATV1 Messages in long format, i.e. the error text (default)
