Hi Ian,

# cat /etc/ttys
ttyU0 "/usr/libexec/getty 3wire.115200" vt100 on secure
ttyu0 "/usr/libexec/getty 3wire.115200" vt100 on secure
ttyv0 "/usr/libexec/getty Pc" cons25 on secure
ttyv1 "/usr/libexec/getty Pc" cons25 on secure
ttyv2 "/usr/libexec/getty Pc" cons25 on secure
ttyv3 "/usr/libexec/getty Pc" cons25 on secure
ttyv4 "/usr/libexec/getty Pc" cons25 on secure
ttyv5 "/usr/libexec/getty Pc" cons25 on secure
ttyv6 "/usr/libexec/getty Pc" cons25 on secure
ttyv7 "/usr/libexec/getty Pc" cons25 on secure

Only USB TTY port works.

If I do something like:

echo "test" > ttyu0

Nothing is printed on the serial port. Don't know why.

ps auxw
