Connection INSYS GPRS 5.0 serial

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.
