I explore anything from here and Google ...except very expensive ActiveXperts Serial Port SDK I cannot find anything more complex than PHP native fopen.

I found this here, but nothing happend...no error trigger nothing

$serial = new DOTNET('System', 'System.IO.Ports.SerialPort');
$serial->PortName = 'COM1';
$serial->Open(); 

Please give me a clue about how to implement this.

Answer 1

You could use

$serial = new DOTNET('System', 'System.IO.Ports.SerialPort');
$serial->PortName = 'COM1';
$serial->Open(); 

and then and

$serial->Write();
$serial->Read();

If there is no error is worth a try.
