The successful dial-up into the GPRS network is displayed after the startup with
the message +PPP-IP SETUP; the INSYS GPRS 5.1 serial can now be reached via its
IP address.
If the connection can not be established (network failure, etc.) or if the connection
is terminated, the INSYS GPRS 5.1 serial will automatically start reconnecting.
To limit the connection costs for failed connection setups (for each connection
setup data packets are created and billed), the delay time will increase for every
new repeated attempt.
 20 seconds after restart or if the last connection setup was successful
 80 seconds after the first failure
 320 seconds after the second failure
 1280 seconds after the third failure
 1 hour for each additional failure
