Here is an up-to-date (as of 1.3.66) version of serial console patches
originally made available by Miquel van Smoorenburg (Thanks!). These
patches have been working flawless for my three Linux-PC's since they
first hit the net. All i did was to keep them current (read: resolve
conflicts with subsequent kernel patches). The do apparently work on
SPARC too (also the attached patch might be needed) and do at least
compile on the Alpha (I couldn't find the time to rig a spare terminal
to actually test it...)
Linus, also you have already announced the CODE-FREEZE, please consider
to include these patches, since they will increase Linux' versatility,
especially for ISP's and large sites! (And to second Alan Cox: Please
consider to include the accounting patches as well, without them Linux
is not suited for commercial use. At least not in the eyes of those bean-
counters in the financal depts.)
Yours,
Dominik Kubla
PS. As long as this is not included into the mainstream kernel, i will try
to have a patch against the latest official kernel at:

I just re-enabled the already existing serial console driver. Sparc-Linux
had the problem, that if no frame buffer device existed, it halted the
kernel upon boot time. So my patches are really small ;-)
