I'm attempting to attach a Calcomp 2000 graphics tablet to a 
6150 runing 4.3 via the planar serial port.  I would like to use
the TABLDISC line discipline.  Everything works as it is 
supposed to, provided Xibm is not running.  If the X server is running,
reads on the serial port block.  In addition, the stylus for
the graphics tablet appears to control the X cursor... but incorrectly.
Any stylus motion moves the cursor to the bottom right hand 
corner of the display.  So it appears the X server is intercepting 
the tablet input. Whether deliberately or inadvertantly, I do not know. 
This would be acceptable behavior, provided it worked correctly.
Any information regarding what is supposed to happen would be
greatly appreciated.
