Cellular shield with SM5100B

Good morning,

I have a problem with the modem in the subject. I have a project that needs to make two things:

  1. send some data on an FTP server, and I can this .

  2. Establish a pont to point contact with a PC, responding to a GSM data call. I have tried to call this modem with the internal modem of my Notebook, but the modem reply me ever as if the call is a data call.

Is it possible that this modem doesn’t support the data call type? I have read the datasheet of the modem, the AT command list, but I’m been able to solve the problem.

Thanks at all.

Best Regards,
