Touchscreen troubles...

I am having problems getting a Dynapro SC3 touch controller working with
QRTP. I am using a 6.4 inch screen at 640x480 video resolution.

I run the following (controller hooked up to COM1):

devc-ser8250 -b 2400 &
devi-dyna dyna -b 2400 fd -d/dev/ser1

I get a cursor, but it doesn’t follow where I press on the touchscreen.
Occasionally QRTP will start an application or something as I randomly press
around on the screen. So I run calib and it shows me the target. When I
try to press on the target, nothing happens. So I press elsewhere, and if I
tap randomly around it will eventually move the target, but the finger
presses never match the target. And the mouse cursor is sometimes on the
screen, sometimes off the screen depending where I touch the screen. I put
it on a serial port monitor, looks like the SC3 is sending 6 bytes when the
screen is pressed, don’t know the format to check it, but the serial port
parameters seem to be correct. Any clue what is wrong? BTW, this worked
fine under QNX4 and Photon 1.14.

Let me have a look at this,
we will try to reproduce the problem here and get back to you.

Thanks
