Serial Remote Control
With this little software you can command your Touch Screen as sold by Legamaster.
The layout is like the original.
This version only works via serial RS232 connection.
If you do not understand how this works then this is not for you.
If your size of screen does not react on a button, then the screen does not support the function.
Or you're to fast pushing all buttons after each other, so give it a little time.
Not all screen sizes bare all the same functions.
This software comes as is, without warranty and without support.
You need to have a direct RS232 connection from Mac to the screen (possible with usb2serial).
Or you setup a program to create a virtual com port and use your TCP output to the screen.
If you have questions: Google or better DuckDuckGo is your friend.
