I have a bugfix and some additions to the z8530 driver
(linux/drivers/char/scc.c). It has it's own MAJOR number now,
instead of the "borrowed" MINOR numbers from serial.c.
Is character device number 22 okay?
This patch includes one for linux/arch/i386/config.in so that one
does not need to include AX.25 kernel support to use the Z8530 driver,
some people (me too) prefer to use WAMPES or any other KA9Q NOS
derivate for AX.25.
Some few changes in README.scc, too. (esp. my email address)
Well, that's it.
