Hi,

I had some problems with mice a while ago. I found that my Logitech
Series 9 mouse wouldn't work without having DTR and RTS cycled at it,
and sending "*B" (I think). I modified my copy of the mouse server to
do this; I'll see if I can dig it up for you.

Otherwise, I had no problems with my very old Genius mouse; I guess it just
depends on lots of detail...
