The above description is not exactly correct. If you ever want to use
mouse in syscons, you must run moused and let X access the mouse
through /dev/sysmouse. If you don't need the mouse pointer in
syscons, you can let X directly access the mouse.
You have either
Std Mouse -> COM1 -> moused -> /dev/sysmouse -> X/syscons
or
Std Mouse -> COM1 -> X
If you run moused on COM2, mouse events it detects will also go to
/dev/sysmouse.
/-> /dev/sysmouse -> X/syscons
Mouse Remote -> COM2 -> moused -
\-> /var/run/MouseRemote
Then, if you run two copies of moused, you get
Std Mouse -> COM1 -> moused -
\
-> /dev/sysmouse -> X/syscons
/
Mouse Remote -> COM2 -> moused -
\-> /var/run/MouseRemote
If you move the standard mouse and mouse part of Mouse Remote, you
will see "combined" motion of the mouse pointer on screen. However,
mouse events from the standard mouse and the Mouse Remote are NOT
messed up, because events from two devices are interpreted
independently by the two copies of moused.
Apart from possible RF interference, there is a case you may think
your mouse pointer is jumpy. You may perceive the above "combined"
motion as "jumpy", because you think the mouse pointer has moved when
you don't touch the mouse, but, in fact, you may have touched or moved
the other device accidentally.
