Hi all.

I'm trying to get the console working via the Service Processor on a
Sun V20Z. I have enabled console redirection with:

platform set console -s sp -e

I then attach to the console with:

platform console

... but when I cycle the power (from another window: platform set power
state cycle), I end up with screens full of garbled characters instead
of the startup/BIOS screens.

localhost $ platform console
[Enter `^Ec?' for help]
açæxæ~æaçæxæ~æaçæxæ~æaçæx

[...etc...]

Does anyone have any idea about the likely cause of this problem? I am
using a vanilla xterm window with TERM=vt100 or TERM=xterm (it doesn't
matter which).

Regards,

Robert.

Robert,
make sure you check the speed setting (9600) of the sp,
and match it exactly with the bios setting for the serial
console.

What I found was that I had to plug in a keyboard and monitor
to get things setup initially (set console redirection ON, 9600,
no flow control, use the "enhanced pc" option for the console and
definitely NOT the utf8 option), then I had to poweroff the unit
completely and poweron without the keyboard or monitor attached.

a real pain, but at least I got a working "serial" console.

failing that, log a call with Sun

Thanks! This was exactly the fix.

platform set console -S 9600

Cheers,

Robert.
