Hi smainj,

to complete the message of zorx, unfortunatly there is no download available at this time.

So by using SVN, this is the last source in attachment, i have not tested, but normally should be functional.

Best regards

May I ask what you need PHP in connection with the serial port for ?

If you want to monitor, you can use any MySQL DB and a sniffer
Program ?

Hi,

I have found a PHP instruction to read RS232 in library Direct IO. http://www.php.net/manual/en/book.dio.php

Here is an example:

Code:

<?php
 
exec('mode com1: baud=9600 data=8 stop=1 parity=n xon=on');
 // execute 'help mode' in command line of Windows for help
 
$fd = dio_open('com1:', O_RDWR);
 
while (1) {
 
  $data = dio_read($fd, 256);
 
  if ($data) {
      echo $data;
   }
 }
 
?> 

You can found more explications in : http://www.php.net/manual/en/function.dio-tcsetattr.php#51509

Best regards.

thanks for your help
working code

<?php
    // Use this code to write directly to the COM1 serial port
    // First, you want to set the mode of the port. You need to set
    // it only once; it will remain the same until you reboot.
    // Note: the backticks on the following line will execute the
    // DOS 'mode' command from within 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 {               
        $string  =   "Send"  ;       
        echo $string;
        fputs ($fp, $string );       
        sleep(5);
        $buffer = fgets($fp);
        echo $buffer ;
        fclose ($fp);
    }
?>
