    Is there a resource that details the AT commands available?

    Hi Stuart,
    The current wireless modem on the iSMS is the GPRS G2 Modem. Below is a link to document that covers this modem’s AT commands. The previous F4 modem also uses most of the same AT commands.

    Excellent information.

    Should the AT commands be passed to the device as part of a standard messasge?

    Hi Stuart,
    AT Commands can only be sent to a modem using the TCP Connection feature, which directly connects you to the modem. When the TCP connection to a modem is active, the iSMS has no control over that modem until the TCP connection is ended, so all messages would have to be manually sent and received using AT commands while the connection is active.

    You can test this feature by opening a telnet session on the iSMS to port 5000. Port 5000 is for modem 1, up to port 5007 for modem 8 (on a SF800).

    Regards,
    Bryon

    Very interesting.

    I will experiment with that.

    I am hoping to create a web page that will be regularly reporting statistics on the iSM, especially signal strength.
