ARRCOM SBC-GX Development Kit - Touch Screen

Has anyone gotten the touch screen to work under RTP for the development
kit? The documentation is iffy, one place doesn’t say much and the other
says its not supported. There is no mention of what driver to use, the
documentation says:

"
The four wire analogue resistive touchscreen interface can be used in place
of the standard com3 RS232 interface. …
The touch screen controller contains a 8-bit analogue to digital converter
and transmits a serialised bit stream corresponding to the A/D outputs. Each
time the touch panel position is reported, the X co-ordinate value is
transmitted as an unsigned 8-bit value followed by the Y co-ordinate value,
which is also an unsigned 8 bit value. The Y coordinate value is then sent
again to distinquish between X and Y values.

The serial data is trasmitted at 4800, None, 8, 1
"
And the serial port has been set to IRQ 11. Does this format correspond to
any of the existing RTP touch screen drivers?

I guess, no.
