cwilt on DEV-11712 - pcDuino - Dev Board

Anyone else looked at the sample provided for uart?

#!/bin/bash
cd `dirname $0`
if [ $# -ne 1 ]; then
    echo "Usage: $0 MESSAGE"
    exit 1
else
    msg=$1
fi
delay=3
uart_id=1
rate=115200
setup()
{
    uart_id=1
    delay=3
}
loop()
{
    echo "connect your PC with the board via uart${uart_id}, baund rate $rate"
    sudo rmmod sun4i-gpio -f 2>/dev/null
    sudo chmod 777 /dev/ttyS${uart_id}
    killall microcom > /dev/null 2>&1
    killall busybox > /dev/null 2>&1
    busybox microcom -s $rate /dev/ttyS${uart_id} 2>/dev/null &
    while [ 1 ]; do
    echo -e "$msg\r\n" > /dev/ttyS${uart_id}
    sleep $delay
    done
}
main()
{
    setup
    loop
}
main

This looks like a bash script and nothing like arduino C style code. I posted on the pcDuino forum and waiting for a reply.

What am I missing? Maybe Sparkfun knows something?
