Hi,

I have a 12.1" TFT with touchscreen with RS-232 connector, but can't get it running on SuSE 8.1.

I already made sure:

• to add the usual lines to XF86Config
• drivers are in /usr/X11R6/lib/modules/input
• the touchscreen gives signals with od -h -w10 </dev/ttyS0

The drivers, I've tested are:

• elographics_drv.o
• microtouch_drv.o
• gunze_drv.o
• mutouch_drv.o

Using the ELO driver, the X logfile gives back something about "hw-id not correct", the Gunze driver doesn't return any errors.

From what I see, the display isn't one of the marques above; it looks like this one: godwing.com/1248F.htm, and the *.inf file for the windows-driver mentions
which leads me to believe, the serial controller has been manufactured by sena.com, and the touch-element by hantouch.com (their logo came with the windows-driver).

(none of the above websites offer Linux drivers, other than Sena; but I don't understand if one of the Linux-downloads is right for me)

Does anybody know, what chances I have to get it running? The monitor itself works fine, but pointing on the screen doesn't

Is there a touchscreen driver for above mentioned components, or can I derive one of the existing ones?

i would like to help you, but i have the same problem here.

I thought I would bump this very old thread because I am having the same issue. I have a Toughbook CF-M34 with a "dumb" serial touchscreen that is not automatically recognized by HAL (if you try to probe the serial interfaces, it doesn't show any devices attached). However, running cat /dev/ttyS2 (it's hardwired to COM3), outputs very human-readable touch/release and coordinate information, like so:

I've been scratching my head about this for months. Apparently, the gunzets driver is too old to provide for the latest xorg and doesn't work, and besides evdev and evtouch (which I haven't gotten to work right), there aren't a whole lot of other options out for this.
