This my first API/utilities and lua scirpt ever! :)/>/>. I think there are others and better programms or API's for this, but anyway I thought I upload it! So here it is… :)/>/>

Feature:

- a receiver function with adjustable passcode/password to open/close a door on defined side
- "log" on the receiver screen
- adjustable PCinfo (a PCinfo.txt in /)to identify the receiver
- a Connection Terminal
- check the available status of all PC's using the receiver function

functions():

connect.receiver((string) modemside, (string) redstone-out, (int) loop, (int) usepassword, (string) password, (int) terminateable)
connect.terminal((string) modemside)

Code (litte bit disorderly ;)/>/> ) :
