 I have changed everything to point to /dev/ttyS0.  The settings in
lilo.conf (I am booting from a floppy to emulate the embedded space) are
all for ttyS0.  Lilo pritns to the terminal (minicom on another Linux
box) and the kernel prints as well.  When I get to inittab (running
busybox) it asks for some input thru a script to setup the embedded
emulation.  At this point it just sits there.  If I turn on the debug in
serial.c I can see the characters (hex values) as I type.  Kernel 2.4.2
works fine, with the only problem being the smp compile issue.  As I
need module support and cannot have a kernel of 600k+ size I am in a bit
of a pickle.....

On Thu, 19 Apr 2001, Marc Karasek did have cause to say:

Most gettys and such take a /dev/tty* argument, which has to be changed
to
point to the serial port for a serial console. Config scripts (and
anything else) specifically using /dev/tty or /dev/console should work
fine, however. (I wouldn't recommend pointing a getty at /dev/console -
we
had some issues on a headless server trying that. Easiest to point it at
/dev/ttyS0 or whatnot.)
