How modify GPL source TL-MR3020

I would like to know if it is possible to add a particular web configuration page to a gpl product (such as tp link tl-mr3020 http://www.tp-link.com/resources/gpl/150Router.tar) in order to add support for sms and fax sending through at command. thx

You could, but it would be much easier to modify the infinitely better documented and supported OpenWRT:

http://wiki.openwrt.org/toh/tp-link/tl-mr3020

thx for replying but there is no support in for my usb 3g modem neither in openwrt nor in current tp-link mr3020 firmware. so i would know if there would be possible to add a simple html page as

Code:

<html>

 <body>

  <h1>SMS</h1>

  <form method=post action='sendsms.php'>

  <table border=0>

  <tr>

    <td>Recipient</td>

    <td><input type='text' name='recipient'></td>

  </tr>

  <tr>

    <td>Message</td>

    <td><textarea rows=4 cols=40 name='message'></textarea></td>

  </tr>

  <tr>

    <td> </td>

    <td><input type=submit name=submit value=Send></td>

  </tr>

  </table>

  </form>

 </body>

</html>

in order to send an sms or AT command within javascript in html page to send fax and sms.

I don't understand, if there is no support for your hardware, how will you send the AT commands to it?

I should sniff usb traffic in order to grab some datas that would allow usb modeswitch to support my hw and as so on...
