4.6.1.1  Offline 
The offline command mode is the state after the GSM/GPRS engine 
was booted and initialized, or after a reset of the INSYS GPRS 5.0 se-
rial. During the offline command mode the INSYS GPRS 5.0 serial can 
be addressed via AT commands. 

4.6.1.2  Online 
The INSYS GPRS 5.0 serial can be switched to online command mode 
during a data connection (CSD, GPRS, “TCP transparent”). 
After switching from data mode to online command mode, the con-
nection will remain established, but no data is transmitted to the 
remote terminal. The online command mode is also entered by DTR 
drop (setting AT&D1) or by activating the reset input twice within 10 
seconds. 
Note:  Terminating connections see Chapters 4.2.6 and 4.4.4  

Depending on the connection type, the data is transformed unal-
tered from and to the application (CSD call, GPRS call) or processed 
by integrated TCP/IP stacks of the 

µ

controller (TCP transparent).
