Hello All,

Please apologize if this request is wrongly placed. I'm not familiar with programming, just a keen user. I'd be thankful, if anybody could point me into the right direction.

I'm using X (4.3.0) on Linux, and I'm struggling to get a touchscreen (-input) device to work. It's not one of those popular manufacturers whose driver is included with 4.3.0

Things I've found out yet:
manufacturer of the 12" TFT monitor with touchscreen is a no-name Asia-based. The 
interface is RS-232 with 9-pin serial connector and a PS/2 dongle-style plug (the mouse 
plugs into the back of this plug).
Touchpanel manufacturer is a company called Hantouch
Serial driver PCB manufacturer is a company called Sena
(both companies offer downloads, but I didn't found any for X)
The monitor is marketed under the label Glancetron in Europe
(They only offer Win drivers unfortunately)

Since I haven't found any *nix drivers on the net, I've tested all input drivers which 
came with X.
None of the touchscreen drivers work, some cause X to abort.
The only reaction I get is from the DigitalEdge tablet driver, which causes a 'click' 
in the bottom right corner of the screen, no matter on which area I touch it.

My question is:
Would it be an easy task to modify an existing driver to get the touch element to work?
I've had a look at the Elotouch driver sources, and it doesn't look huge. I have no 
idea about programming, but I'm motivated to take the challenge.

Sure, but you need to know what the incoming packets look like. Have you dropped a line to Hantouch? If you have, and they're unwilling to help, you probably can track RS-232 communications between the touchscreen and the Windows driver...

Good luck!
