no, it's not a baud rate or parity issue. if you look closely at the
serial output from one of your working machines, you'll see that the
very first character produced by OFW is '+'. <cr><nl> or <nl><cr> is
next, then the Forthmacs strings. i believe mitch uses every one of
those characters as a progress indication. dying as early as your
machine does is probably not a good sign.
