Execute command

ATZ[]

Response

TA sets all current parameters to the user profile stored with AT&W (see Chapter
2.38 on page 34). If a connection is in progress, it will be terminated. All defined
GPRS contexts which are not activated or not online will be undefined (see
+CGDCONT,+CGQREQ,+CGQMIN commands). 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 ad-
ditional 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 cor-
rupted.
