Data from web servers arrives at modem, Modem handles it over to some other program for the Protocol Stack and finally submit to the reuqesting applications.<br>I needed to keep a check on all the data coming through modem looking for a particular signal.That should be done before data gets distributed between applications and even before it is passed through the protocol stack.<br>&nbsp;&nbsp;&nbsp;&nbsp;In other words, &quot;How to take data for some searching through it as soon as it is available from the modem, after search handle it over to the operating system for further routine processing&quot;.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;How could I do this, or Where should I start from?<br>
 
Well, i am not sure of the exact way to do that programmtically but to see the data you can install a packet sniffer on your machine. The one i have is from Network Associates, i have only just begun to use it but it seems pretty usefull....... You may have to look into communicating directely with the modem driver. You should also look into the PPP protocol, that is the protocol that controls modem transmission, i think... Do you have a specific language you want to write this program in????? C would be a good choice to start of with, because you can see all the TCP/IP suite code. It is released fully in linux and unix and could help you out perhaps....
