  • Your modem probably has a serial interface, so Your problem is how to communicate with a serial device. Explore for example this project code.google.com/p/php-serial/ – Roman Hocke Jan 08 '14 at 08:44
  • I check out this link you recommended http://code.google.com/p/php-serial/, my question is this php class can send AT COMMAND directly to device, and can you give some example on how to do it? – ani Jan 08 '14 at 08:53
