Hello!
Thanks for the given answers. It was a great help for me. But now, i have again one problem:
When I read the NMEA-protocoll from the server by using the client-object and filestream.readstring over a GPRS-connection, i can take the data without problems. But if I dont' read the data form the server for perhaps one minute, the server will send me the NMEA-protocoll from one minute ago. If I wait three or four minutes and read then the filestream, i don't can take the actuell data, only the data from the time, i have stoped reading. The administrator from the server said, that the server doesn't buffer the data. Is it possible to make a reset, when i begin to read from the stream?
thanks for help....
