I have tried cons25, xterm and (now) vt100. It's not that...
# Serial terminals
# The 'dialup' keyword identifies dialin lines to login, fingerd etc.
ttyd0 "/usr/libexec/getty std.115200" cons25 on secure
ttyd1 "/usr/libexec/getty std.9600" dialup off secure
ttyd2 "/usr/libexec/getty std.9600" dialup off secure
ttyd3 "/usr/libexec/getty std.9600" dialup off secure
# Dumb console
dcons "/usr/libexec/getty std.9600" vt100 off secure
# Pseudo terminals
ttyp0 none network
/etc/ttys: 307 lines, 7539 characters
(root|bone)/home/mrboo# kill -HUP 1
(root|bone)/home/mrboo# ps ax | grep getty
21134 p0 R+ 0:00.02 grep getty
(root|bone)/home/mrboo#
Note: I have no getty processes as there's no graphics card, so I am
guessing if it was working right I would start to see a:
/usr/libexec/getty std.115200 ttyd0
It appears in the process list (and works) when I run the above manually!
