A few notes.

As soon as I am feeling well enough I need to move the Debian packages
to 1.20 now that woody is solidly frozen.

The sequences are documented in several places for ps2, sadly some mice
have really nasty problems with commands other then those for setting
the rate.

Including not being able to handle the reset command.

Thankfully those are pretty much limited to the OEM logitech mice.
(These are the logitech mice with either a black and white logo on the
top or the logo as a sticker on the top, these are rebranded as HP and
compaq mice among others. The suggested fix is a sledge hammer.)

I would be /very/ curious to know if the Debian gpm sources[0] work
properly with his mouse.

They just might.

[0]: ftp://ftp.debian.org:/debian/pool/main/g/gpm/, you want
gpm_1.19.6.orig.tar.gz and gpm_1.19.6-12.diff.gz, untar the orig, apply
the diff, unpack the contents of the upstream/tarballs directory, apply
(in numerical order) the patches in debian/patches, compile[1].

[1]: Yes, this whole thing is completely automated for me, but if you
don't have a Debian system handy it is the method guaranteed to work
more or less.

}Wow; in that case, my physics degree is *WAY* more useful than I
}had thought.
This just proves how useless a computer science degree is:  there is hardly
any useful science involved at all.  I want my computer black magic degree!
