I had a lot of problems with an Ultra 10 and the serial port A. The
solution I used was:
1) Plug in a Sun keyboard.
2) Before booting, Hold STOP and N and do not release them until the
machine booted. This will reset the NVRAM. Ordinary users typically do
not have brand-new Sparc, only second-hand machines and you never know
the previous settings.
3) Without seeing anything, type STOP and A simultaneously. You will
go to the boot prompt (but, without a Sun monitor, you will not see
it). Then type:
setenv output-device ttyb
setenv input-device ttyb
reset
Then, the second serial port, B, which uses a much more common DB9,
should work.
