ELO touchscreen setup (debian)

From Rivendell Wiki

I was able to get the touchscreen working with one of the test boxes. Here
are some basic notes.



Using serial connection
NOTE: If an active USB cable is plugged into touchscreen the serial port is
disabled!

MaxX, MinX, MaxY & MinY option settings are pretty close but proper
calibration is best.
There is a program on sourceforge that we could build that will get us the
calibration.
