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
