[SunHELP] Sun E450 serial console problem

[Mikhail Emelchenkov]

Hi again, Fred,

I got the keyboard and did NVRAM reset (Stop + N). Nothing changes. Then I
pressed Stop + A (blind, because I dont have VGA adapter), changed port to
ttyb, attached my USB serial to appropriate pins, and I got trash instead of
correct characters again. It seems port is broken, but how it could be broken,
how to fix it?
