PHP Serial Class for OSX
by Rizwan Kassim on Nov.18, 2009, under Tech Articles
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 Rémy Sanchez’s PHP Serial class.

Description
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
Windows.
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
device.
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.

Tweeting along- Anyone *love* their 3G data plan? Turns out AT&T requires a 2yr commitment, even if I use old equipment - not interested...

- @heathervescent I hear you. I feel like a well intentioned foreign exchange student half the them. Thankfully people are often kind.

Hi, I’m interested in submitting some code changes to the php_serial page on Google, but I’m not sure how to go about doing this. I’ve only been playing with this code for a short while, but I’ve found a number of things that need changing to make it work better on the Mac.
The google page doesn’t give any way to submit changes, any help would be appreciated. I’m going to be offline a bit during the holidays, but I’ll get the changes to you as soon as I’m able.
