Re: dial-up in uClinux

You should not use PPP, as PPP will do too much thing than normal GPRS connection.

For connection with GPRS: you need two AT commands:
AT+CGDCONT=1,IP,156.090.123.076
ATD*99#
Please note that the above two is just a example, you need to consult your operator for the actual one.

After this connection, the system can now on the internet world, you can do the TCP/UDP/IP... protocol
