From what I could tell trying to get X running, it is not the kind of mouse
being used but that there must be a valid (i.e. existing) device specified.
In the second example above, /dev/ttys2 must be a valid entry in /dev and
there must be a serial port associated with the device. X does not seem
to mind if there is no mouse or any other object connected to the port,
just that the port functions correctly.
As to which one to use, you need to specify the device to which your
mouse is connected. I believe that /dev/mouse is used for the logitec
bus mouse (when apropriate kernel patches to support it are applied) and
/dev/ttys2 and /dev/tty65 are both names that people use for the second com
port. I don't know what the major/minor numbers for com ports are off
of the top of my head.
One other note: I was not able to get a stable screen display until I
trimmed the virtual size of the screen to be the same as the physical
size (i.e. 640 x 480 or 800 x 600). This was for an Orchid ProDesigner
card, ET3000 chipset.
