Did you hold the port open between the two stty commands? As soon as
the port closes it's going to go back to its default settings. Try
this:
sleep 60 < /dev/tty00 &
stty -f /dev/tty00 clocal
stty -f /dev/tty00

That sounds correct.
>Tip doesn't work either. Ttyflags, on the other hand does work.
>I'm running the i386 port.
If I'm not mistaken, ttyflags changes certain defaults for the ports.
Did you try adding "local" to your /etc/ttys file? I. e.
tty00 "/usr/libexec/getty std.115200" vt100 off local
You might also want to add "softcar" if you don't have a real modem
(or a modem that doesn't assert carrier detect properly) on that port.
Do "man ttys" for more info.
>Any suggestions? Is there a problem with the com driver, tty code or me?
It sounds like the com port is working correctly.
