Hello I have tried pretty much everything at this point... My problem is that the TC65T modem doesn't "understand" the AT-commands that I send from the S7-200 (via the PPI cable), or at least that is what I think is my problem. I can connect the S7-200 to a hyperterminal in windows (again via the PPI cable) and I do recieve the AT-commands that I send from the S7-200 (port0), and I can also respond to the S7-200 via the hyperterminal. I can also send AT-commands from the hyperterminal to the TC65T modem, and make it respond to these commands (e.g. at+ipr=9600). But I cannot make the TC65T react to AT-commands send from the S7-200. (I think that it has something to do with the way I send the commands from S7-200, if it should be sent as a string, HEX, ASCII or UFT16 etc.) Can anyone help me? A few points on what I have already tried:
(FYI: I want to use the TC65T as a SMS device, so that I can get updates from my system if any errors occur)

I have spent a few days reading different topics in the forum... with no luck... I have tried using the principle in this approach, the problem is however that he is adressing the problem of configuring the modem to be able to log on to the providers network (accepting the PIN code, etc) My problem is not loggin on to the network, but to be able to make the modem react to the At-commands that I want done when I sent then from the S7-200. Is there another modem that you can recommend, that will make it possible for me to sent sms'es from MicroWin? Kind regards Strand |

I have tried using the initialization program that are available here, but again with no luck. I have also tried implementing the basic structure of this initialization program in my own program, again with no luck. Best regards Rune Strand
