I have compiled a 2.4.2 kernel with the Magic SysRq key enabled, but I
don't seem to get any response to it from either the VGA console or
the serial port. I have read Documentation/sysrq.txt and can't
understand what I'm missing here...
I assume I should be attaching a NULL modem cable to the serial port,
correct? I am doing this, and using C-Kermit to send a break signal
followed by e.g. `t', but nothing comes back. :-(
Likewise, trying Alt-SysRq-t (or whatever) from the text-mode login
prompt, or from a text-mode shell, doesn't do squat. The machine is
not hung or anything -- it is otherwise working fine.
Note that it's the serial support I am most interested in having
