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

	sleep 60 < /dev/tty00 &
	stty -f /dev/tty00 clocal
	stty -f /dev/tty00

That sounds correct.

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.
