Yes.  I was impressed when I compared Sun's pinout with the spec and
discovered they'd used the standard-specified secondary pins for serial
port B.

I give Sun credit for, if nothing else, bothering to actually read the
standard, which far too many people supposedly implementing standards
apparently don't do.
