Below is an archive of my PHP Serial Class page from my old site.
The data below is still valid, but the project as a whole has been ported to Google Code. Check there for updates.
Added support for OSX to RÃ©my Sanchez’s PHP Serial class.
php_serial.class.php.gz (3.7 kB)
Gives serial access to PHP under linux, OSX and Windows (write-only under Windows).
This class can be used to communicate with a serial port under Linux, OSX or
It takes the path (like “/dev/ttyS0″ for linux or “COM1″ for windows) of serial
device and checks whether it is valid before opening a connection to it.
Once the connection is opened, it can send data to the serial port, and read
answers (reading is only implemented for linux).
The class may also change connection parameters for the given serial
The example script:
<?php include "php_serial.class.php"; // Let's start the class $serial = new phpSerial; // First we must specify the device. This works on both linux and windows (if // your linux serial device is /dev/ttyS0 for COM1, etc) $serial->deviceSet("COM1"); // Then we need to open it $serial->deviceOpen(); // To write into $serial->sendMessage("Hello !"); // Or to read from $read = $serial->readPort(); // If you want to change the configuration, the device must be closed $serial->deviceClose(); // We can change the baud rate $serial->confBaudRate(2400); // etc... ?>
Changes in this version.
