I have created a few scripts for controlling a VEX micro controller connected to a linux host.

==vexphp==
I have created a simple class of PHP functions for doing fun things like controlling your robot via a http interface.

==bash script==
Here is a quick bash script that can be used to configure your serial port and do some testing.

TTY=/dev/ttyS0
PORT=$[$2-1]

if [ ! $1 ]; then
        echo Usage:
        echo "vex [device] [number] [command] eg: vex port 1 on OR vex motor 2 down"
        echo "vex [command] (prepare,init,exit,reset)"
	exit
fi

if [ $1 = "prepare" ]; then
	stty -F $TTY 115200 -parenb -parodd cs8 -hupcl -cstopb cread clocal -crtscts \
