TCP server command read
hi!
i use tcp server gsm.. works great how read command client?
i use php script:
and use sim900 gsm modem gsm gpr sgps ide100 v307 library
so send command php , in arduino tcp server serial monitor
but how command?
sorry english

<?php

}
$message=$_post['message'];
// write message to socket server
fputs($fp,$message);
// get server response
//$ret=fgets($fp,1024);
// close socket connection
fclose($fp);
echo '<h1>you entered the following message in
lowercase :'.$ret.'</h1>';
exit();
