Ok, that cleared a bit for me, tty is indeed the terminal, not an
serial device port on OpenBSD. It should be something like /dev/cua00,
but that doesn't work either:
[EMAIL PROTECTED] 13 ~# ./test.sh
x11x00x00x00xB6x00x00x00xC7dd: /dev/cua00: Device busy
Please forgive me, since I'm a Mac user, I'm not too familiar with
this stuff.
Here's my dmesg output, booting OpenBSD on the soekris:
