How are you submitting the form?

<form action="myfile.php" method="[B][COLOR=red]???[/COLOR][/B]">

I'm betting you're using POST, which means you need to change $GET to $POST.

EDIT: Also note that devinemike forgot to escape his slash, so that "c:serial" in his post probably meant "c:\serial" !

thanks for all of those who answered me.

As an answer i was using <input type="submit" value="get">
in the form sorry for not writing that!

Should i write exec("c:\serial.exe"); or
exec('c:\serial.exe'); as i was told?

Either will work, take a look at the section on a [man]string[/man] in PHP for more information, but basically, use double quotes if you want PHP to evalulate variable names (as in your case), or just single quotes so that no evaluation is done.

Also.. I was asking about how you submit the form, which is configured in the FORM element, not the INPUT...
