2.33 ATZ Set all current parameters to user defined profile
Execute command
ATZ[<value>]
Response
TA sets all current parameters to the user profile stored with AT&W (see Chapter
2.39 on page 37). If a connection is in progress, it will be terminated. The user
defined profile is stored to the non-volatile memory.
Note: If invalid, the user profile will be reset to the factory default profile. Any
additional commands on the same command line will be ignored. A delay of
300 ms is required before next command is sent, otherwise “OK” response may
be corrupted.
OK
Parameter
<value> 0 Reset to user profile
Reference
V.25ter
Note
The GSM engines referred to in this manual can be assigned two profiles: the
factory profile (restored with AT&F) and the user profile (stored with AT&W). See
Chapter 2.36 for details on AT&F.
2.34 AT&C Set circuit Data Carrier Detect (DCD) function mode

This parameter determines how the state of circuit 109(DCD) relates to the
detection of received line signal from the distant end.
OK
Parameter
<value> 0 DCD line is always ON.
1 DCD line is ON in the presence of data carrier only.
Reference
V.25ter
Note
Line state refers to RS-232 levels.
