I have installed Slack 12 with PS2 mouse but now I'd like to switch to serial.
I found the script /var/log/setup/setup.mouse , which I ran
tried ms msc bare but nothing.
tried changing /dev/mouse->/dev/input/mice to point to /dev/input/mouse0
but that always reverts to /dev/input/mice after reboot.
after fiddling with these for a while and using minicom to set the serial port to 1200, I had the cursor moving after I ran /etc/rc.d/rc.gpm restart,
but only until reboot ( and a break forgetting what just transpired. )

So now I looked at /etc/rc.d/modules-2.6.21.5.smp
(thought I chose non SMP kernel , at least the first time )
which was probing for ps2mouse comented it out , uncomented modprobe sermouse, but after reboot lsmod still shows psmouse module loaded but no other mouse???

Another odd thing is that serial 1 is not in the /proc/interrupts.

Any suggestions?

Thanks Sam.

That script is mostly for configuring gpm. Gpm is a program which allows
you to use the mouse for copy and paste in a text console. I don't think
many people use gpm these days.

The reverting is probably done by udev. You could try to comment out a
line in /etc/udev/rules.d/50-udev.rules

# KERNEL=="mice", NAME="input/%k", MODE="0644", SYMLINK+="mouse"

So you really want to use gpm? If you only wan't the mouse to work in X
you should also edit /etc/X11/xorg.conf to change mouse protocol.

I wasn't even aware there was such a module as sermouse. In the good old
days when I used a serial mouse things was simple. /dev/mouse was a
symbolic link to /dev/ttyS0 and the protocol was choosen in XF86Config.

This is probably not essential if you can't cut/paste between consoles,
or can you? Totally forgot what it was for.

I never even looked at /dev/input/ prior to all this and only hoping
mouse0 was a newly found device, although I should have looked at the
creation date.

/ttyS0 yes that makes sense and that's most likely what I did when it worked,
if I can only figure out/remember how to use setserial to init the port to 1200
at boot.

So is modules-2.6.21.5.smp still useful for anything?
Can't remember if my network card worked after install,
but probably didn't even think of trying it.

Thank you for the UDEV info.

It was a long time since I used gpm, but I don't think it was possible to
copy between different text consoles.

I don't think that I have even needed to use setserial to get a serial
mose working. The baud rate should be set by the program opening the
serial port. This program could be X.org or gpm. If you tell those
programs to use the right protocol the will probably also set the right
baud rate.

On my Slackware 12 systems I have both rc.modules-2.6.21.5 and
rc.modules-2.6.21.5-smp which are identical files. I also have a symbolic
link called rc.modules which points to rc.modules-2.6.21.5-smp as I run an
SMP kernel. This seems a bit messy, you could think that a startup script
calls rc.modules which should be a link to the right file. However it
seems as if rc.S first calls /etc/rc.d/rc.modules-$(uname -r) and then if
no such file exists falls back to rc.modules.

My guess is that the ide is that even though rc.modules-2.6.21.5 and
rc.modules-2.6.21.5-smp are identical files you have the possibility to
customize them if you want to play with different kernels. The symbolic
link rc.modules would be needed if you switch to another kernel with
another version.

I'm sure it was, and _is_, possible to copy between different text
consoles.

I commented it out but now my mouse link is removed on boot .
I guess I'll create it in rc.local

Cheers.

That will be too late. In /etc/rc.d/rc.M gpm is started before rc.local
is called, as shown by the following "tail".

kees@lankhmar:~$ tail -n 17 /etc/rc.d/rc.M

# Start the GPM mouse server:
if [ -x /etc/rc.d/rc.gpm ]; then
. /etc/rc.d/rc.gpm start
fi

# If there are SystemV init scripts for this runlevel, run them.
if [ -x /etc/rc.d/rc.sysvinit ]; then
. /etc/rc.d/rc.sysvinit
fi

# Start the local setup procedure.
if [ -x /etc/rc.d/rc.local ]; then
. /etc/rc.d/rc.local
fi

# All done.

You'll need to modify /etc/rc.d/rc.gpm.
Either create the link at the top of rc.gpm or modify the lines in
the "restart" and the "default" sections to use /dev/ttyS0 instead
of /dev/mouse.

Kees.

I'm no expert on writing udev rules, but maybe it would help to write a
new rule looking something like this:

KERNEL=="ttyS0", NAME="tts/0", SYMLINK+="mouse", MODE="0644"

Maybe you will also have to modify the existing rule

KERNEL=="ttyS[0-9]*", NAME="tts/%n", SYMLINK+="%k", GROUP="uucp",\
MODE="0660"

to look something like:

KERNEL=="ttyS[1-9]*", NAME="tts/%n", SYMLINK+="%k", GROUP="uucp",\
MODE="0660"

But as I wrote before, I'm only guessing now and haven't tried this myself.

Lol, in the past, when I heard about kernel rules I though it was makefile related.
I'll try to find out more about this file , but for now I'll probably stick to
scripts.
I have enough ghosts in this 16 interrupt , I810 infested machine, for now.
One of those that reboots when USB stick is inserted.
maybe it's time to

shhhh well maybe I'll try it.
Cheers

Oh, Thank you. That would probably take me another several hours to figure out, lol.
