Of course, not.  That feature is clearly noted as SunOS specific in
the book (I believe FreeBSD supports it, too).

> Huh? What system was this suggestion for? As I understand pseudo tty's,

They are not pseudo ttys in the sense ptys are.  /dev/ttydN and
/dev/cuaN (where N is the port number) are connected to single serial
port, but they have different minor device numbers.  This feature of
SunOS allows the sysadmin to set up the port "bidirectional" so that
logging in from outside and dialing out to outside both work without
having two separate modems for dial-in and dail-out.  Of course only
one direction works at a time.

As to why NetBSD doesn't support the feature, I have no idea.

Did you re-make /dev/tty00?

It's

tty00   "/usr/libexec/getty std.9600"   unknown off secure

by default, but I'd make them insecure which I just did (remove the
keyword "secure" to make it insecure).  Root can log in on secure
ttys, and I don't like the idea that someone can dial-up and log on as
root in the system from outside although, in this case, it doesn't
make much difference since getty on the port is turned off.

For the dial-in ports, the keyword "off" should be turned "on".  Try
"man 5 ttys".
