I have installed xampp in fedora 13.I am trying to communicate with microcontroller through serial port using php serial class. My code is example.php(find the attachment).On opening example.php through firefox the code is being displayed again as shown eviceSet('0'); $serial->confBaudRate(9600); //Baud rate: 9600 $serial->confParity('none'); //Parity (this is the 'N' in '8-N-1') $serial->confCharacterLength(; //Character length (this is the '8' in '8-N-1') $serial->confStopBits(1); //Stop bits (this is the '1' in '8-N-1') $serial->confFlowControl('none'); //Device does not support flow control of any kind, so set it to none. //Now we 'open' the serial port so We can write to it $serial->deviceOpen(); $serial->sendMessage('*1' ); //sleep(1); // echo 'hi'; $serial->deviceClose();?> as u can see the php code is not getting executed. Most of it is displayed again in the browser as shown. The commands are not being sent to the microcontroller. Please help me And is there any other way to communicate to serial port other than php class. Can you please suggest any alternative method?
