Other Help Topics :: 486PC:serial mouse and 3c900b not working
Thank for your tip Modrak,
"Try to do link from /dev/ttyS0 (COM1) to /dev/mouse or /dev/mice"
But I'm not (yet) a linux expert, especially not on devices.
COuld you tell me how to link /dev/ttyS0 to /dev/mouse ?
Simple:
rm -f /dev/mouse
ln -s /dev/ttyS0 /dev/mouse

TyphoonMentat: thanks, this works!
