Hi Miguel, Thank you for your advice; 

No problem for the OS; my Os is windows. 
Do you think that the GPRS connexion depends on the GPS device?
The javax.comm.*, as far as I know, offer 3 connection types: serial,parallel and using sockets.

In my case; I have two parameter for the connexion: the APN and the port number. Perhaps, should I deal with the APN as an URL and the connexion will be set up transparently?!!!!

Just one note. Javax.comm.* only runs on Solaris and Windows. If you need Linux, Mac OS X, ... support, you'll need other "plug-ins" for original Sun package.

Here you have one GPL project we're using at gvSIG[1]

I've not used AT commands and GPRS communications in Java, but have done in C++. One advise: think in all possible problems, link failures, coverage problems, ... They'll certainly happen ;-)
