Listening to USB-COM Ports with PHP

Hey Guys,

 

I know there a quite a few posts about barcode scanners, but most of them talk about the ones that just act as a keyboard.

 

I have a barcode scanner that interfaces with the PC through a cradle which it sits in. It's the kind of scanner you pick up and scan multiple things with, and then put it in the cradle and hit upload. It was supplied with USB-COM port drivers, and propietry software which can interact with it. However, i wanted to write a cutsom PHP script that could talk to the scanner and do specific things. I also don't want to have to pay for the software (and it's limited functionality) :P

 

The barcode talks to the cradle through infrared, and the cradle is connected to my PC via USB. I know the bits per second, data bits, parity, stop bits and flow control needed to talk to the scanner, i just need a push in the right direction for the PHP stuff (if it can be done).

 

Cheers,

Rhys
