There is no need to this... 
when I send an AT-command after ATD*99***1# then I only get very many nice 
characters that makes no sense to me. And after some time the modem says 
there is no carrier.
So I think I shouldn't do to something after ATD*99***1#
There is also the correct ppp-auth-mechanismen that let me think that it is 
connected correctly to GPRS.

in cause of no connection to the ISP. There is no completed ICIP-Stage, so no 
IP-number and no package that was send out and there is naturally no data 
that comes in.
