Me very interested in controling modems via PHP, ASP, PERL and AT Commands. You too! then my project my be for you it's free for testing and research purposes basically its a stand alone server/wrapper for windows 9x to allow you to control modem via scripts etc using ATCommands.
It mainly arose because im going to be geting a nokia 6210 phone soon and want to process SMS messaging via php, but simply could'nt find nothing out their to do the job. Its been tested using a stand modem, but I would be interested in any feed back from people using this server & mobiles phone modems etc.
