I have the device now. I can't test it in Xwin because I still have
problems with XF86Config. (See other mail from me re: XF86Config)

The FreeBSD documentation at :
http://xfree86.pacificrim.net/XFree86/3.1.1/FreeBSD-4.html
suggests that I use "cat < /dev/tty00" (in my case "cat < /dev/ttyd0") to
test the mouse by "just make(ing) sure that it generates output when the
mouse is moved or clicked"

When I do "cat < /dev/ttyd0" the mouse does not generate any output
visible on the screen. When redirected to a file, the file remains empty.
Also, Cntl-D has no effect, so I have to switch to another virtual
terminal to terminate the process with a kill command. Does this mean that
ttyd0 may not be the right device after all?

Thanks again. Ken Marsh
