Serial Communication for Touch Screen Coords

[Guest hawkjm73]

I am trying to use my phone as a music server in my car. The video output works very neatly with the cars screen. I would, however, like to be able to use the car's touchscreen to control the phone. I can get touch coordinates output over a serial port, but I don't know how to get them to the phone. When I tried this with a laptop, I could use Girder to convert the coords to mouse presses. Is there anything similar for PocketPC?

I may need to use a bluetooth serial converter to get the actual data to the phone, but this is much more expensive then I'd like. Is there any serial communication over the data connector, or is it just USB?

I think I have figured out what to do with the data once I get it, but I still gotta get it. Anybody have any thoughts on RS-232 over the data connector?
