5.3.4 Connection to analogue modems
Alternatively, the settings can be entered or modified using the terminal pro-
gram.
To call an analogue modem, an analogue
protocol must be set. While doing so it must
be observed that the remote terminal has to
work with the same protocol as well. AT+CBST=<n>
The protocol V.32 with a data rate of 9600
baud.
AT+CBST=7
5.3.5 Connections to ISDN TAs
Alternatively, the settings can be entered or modified using the terminal pro-
gram.
To call an ISDN TA it is necessary to set the
ISDN protocol V.110. While doing so it must
be observed that the remote terminal has to
work with the same protocol as well. AT+CBST=<n>
E.g.: The protocol V.110 with a data rate of
9600 baud.
AT+CBST=71
5.4 Direct GPRS Connection via PPP
When the GPRS functionality of the built-in GPRS/GSM Engine of the INSYS GPRS
5.0 serial is used directly, the INSYS GPRS 5.0 serial provides only raw PPP data. In
this case, the application must perform the required protocol stacks (PPP, TCP/IP)
for the application. In this mode, the TCP/IP stack of the INSYS GPRS 5.0 serial is
not active.
Example: Connection via the RDT network of a PC.
The INSYS GPRS 5.0 serial is the PPP server in this mode.
