Hi,
First of all thank you very much for replying. I must say I have no experience in serial communication using PHP. I looked at the sites you had mentioned.
what is the meaning of 'write directly to the COM1 serial port'? I used the coding you had mentioned and tried it in my server and the result which displayed was a string that stored in the $string variable.So that`s mean it worked!.
what exectly did this code do?. The code below is what I ran from my server,

<?php
mode com1: BAUD=9600 PARITY=N data=8 stop=1 xon=off;
$fp = fopen ("COM1:", "w+");
if (!$fp)
{
echo "Uh-oh. Port not opened.";
}
else
{
$e = chr(27);
$string = $e . "A" . $e . "H300";
$string .= $e . "V100" . $e . "XL1SATO";
$string .= $e . "Q1" . $e . "Z";
echo $string;
fputs ($fp, $string );
fclose ($fp);
}

please give me some advise.

thanx

This opens the COM1 serial port:
$fp = fopen("COM1:", "w+");
...and this writes to it:
fputs($fp, $data);

And honestly, I have no clue what that code means. 😉

I don't have much to do with serial communication either; that bit of code looks like modem control. I guess what you send and receive depends on what you're using it for.
