SALT Touchscreen driver

Hi All

I need a driver for the Salt Penmount DMC9000.
The Salt website has an option to request it, but so far my three requests have not been responded to.

I am using an Advantech touchpanel PC with one of these controllers connected via serial port (according to the data sheet).
I am running QNX6.1 (old legacy systems that I need to keep running).
So if any one has a driver or source that I can back port I will be most greatful.

Many thanks
