I have a problem with the ppp server. When I receive a data call login it´s ok and the connection is established.
After that, if I make ping from the PC to modem,it responded, but one or two responses properly, stops.
In case of opening a client socket, after the first data, the ppp connection looks good, but no data flow throurgh the socket.
Someone with a client or server on GSM working properly, can give me some light?
The same code works perfect if instead of starting a GSM client/server, stars a GPRS conection or UART ppp server.
