If I have a mouse on serial ttyS0 and run mincom and connect to that port, if I move the mouse around, should I see stuff on the minicom display? I'm trying to work out why the mouse appears not to work.

It is not listed by cat /proc/bus/input/devices.

mounty1,

Maybe. You need set the serial port correctly to communicate with the mouse.
If the mouse sends all non printing characters, you won't see anything.

To test minicom, link pins 2 and 3 on the serial port.
Thats Tx data and Rx data. Everythinf to type will go out of Tx, through the link to Rx and appear on the screen.

I don't doubt that minicom works. It's the mouse that is suspect. Shouldn't it be listed by cat /proc/bus/input/devices ?

Apparently the inputattach utility is required but it isn't in Portage.

mounty1,

Its a wee while since I've used a serial mouse.
When I used one with Xorg, it was with the mouse driver and listing the serial port in xorg.conf.
Thats not so easy today as the auto detect will disable anything with the mouse or kbd drivers.

I suspect that your mouse needs the serial port set to 9600,8N1 with both software and hardware handshaking disabled.

I've never needed inputattach to make a serial mouse work.
