Changing serial port options



I'm trying to change some options on a serial port via stty on 3.2/i386
but it doesn't seem to be working.

sevenn_(_at_)_dub:/home/sevenn> sudo stty -f /dev/cua00
speed 9600 baud;
lflags: echoe echoke echoctl
cflags: cs8 -parenb
sevenn_(_at_)_dub:/home/sevenn> sudo stty -f /dev/cua00 -echoe
sevenn_(_at_)_dub:/home/sevenn> sudo stty -f /dev/cua00
speed 9600 baud;
lflags: echoe echoke echoctl
cflags: cs8 -parenb
sevenn_(_at_)_dub:/home/sevenn>

As you can see, the echoe option is still enabled even tho i've
specified for it to be disabled with "-echoe".  What am I missing here?

The serial port:
pccom0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo

Thanks

-Brian
