Hi, If you have trouble with serial port software in connection with modem, then I strongly suggest you split the problem in two parts: - test you cable and modem using an existing app, such as HyperTerminal; this will also help you in learning modem commands (use on info from Google) - develop your serial port code without a modem, use a second PC (maybe again with HyperTerminal; and with a null modem, or null modem cable) or something else Only once you got both parts sufficiently solved, try to combine your app with the modem. BTW: I advise you to log all serial data (both in and out) in a file using both hex and ASCII while debugging (and to leave the code in, but switch it off, once you think it works adequately). :) Luc Pattyn try { [Search CP Articles] [Search CP Forums] [Forum Guidelines] [My Articles] } catch { [Google] }

This may have nothing to do with your code. Modems have an Echo mode, returning exactly what you send to them. This sounds like your problem. Configure the modem to turn echo mode off, "ATE0" if I recall correctly, in the modem initialization. Of course, the "ATE0" may be returned/echoed the first time, but then everything should operate as expected. You may want to save the configuration after you have done this. Gary

if the end result is not what you want it is wise to look at the intermediate data, in your case log the bytes that the serial port returns to you (I would use HEX numbers). If they are exactly what you have sent, then either your target device is echoing them, or you have an unintended connection between TxD and RxD (transmit data and receive data) on your serial cable. :) Luc Pattyn try { [Search CP Articles] [Search CP Forums] [Forum Guidelines] [My Articles] } catch { [Google] }
