More on the serial strangeness

More on the serial strangeness

[Mike Shaver]

Some better information about my situation, now that I'm not as
rushed:

- I have a serial console on port 1 of the Indy, and I'm talking to it
via minicom on my Linux box.  WOrks great.  Sometimes BRK gets me back
to the PROM, sometimes it just hangs, but I can live with that.
- The boot process goes pretty well, but when I get past the root
mount (using init=/bin/sh), I can't interact with anything.
- I see the `# ' prompt, I get stderr output (!) but the following
commands (which do execute) produce no output:
echo "ttyS0" > /dev/ttyS0
echo "ttyS1" > /dev/ttyS1
echo "cua1" > /dev/cua1
echo "cua0" > /dev/cua0
- If I try to access /dev/console or /dev/tty[1234], I get "can't
create /dev/whatever: Error 19", which seems to be "no such device".

If someone with the appropriate tools could build me a static tail
binary, it'll make the experimentation go a fair bit faster.

I'll be back in Ottawa tomorrow afternoon for a few days, so I'll be
able to work on the console, but since I'll be travelling a _lot_ over
the next few weeks, having the serial stuff work properly is still
important.

I'm still using the dm@neteng 2.0.12 kernel.  Ralf, do you have
anything else built over there you want me to test?

(If it'll help, I can set Miguel and Ralf up with appropriate access
on neon so they can experiment.  It'll take a few days, but if it
keeps those precious geek-cycle from going to waste...)

Two days for that mail?

Btw, Linux/MIPS errno values are (almost) the same as IRIX.

This is the fun part.  You probably need to cheat to make textutils'
autoconf work for crosscompilation.  It's usually ok to run configure on
a Linux/Intel system (Using a glibc system is a good idea) and then
crosscompile with a command like

  make CC=mips-linux-gcc CFLAGS="-O2 -pipe" LDFLAGS="-static -s"

Autoconf is *nice* in almost all cases but it's often a bitch when
crosscompiling, so feel free to use every dirty trick in the book ...

Thanks, would be useful.
