Huh?  Works fine for me (/dev/ttya is hooked up to a VT220):

# stty -a > /dev/ttya
[...]
isig iexten icanon -xcase echo echoe echok -echonl -noflsh -tostop
[...]
# stty -echo > /dev/ttya
# stty -a > /dev/ttya
[...]
isig iexten icanon -xcase -echo echoe echok -echonl -noflsh -tostop
[...]

RTFM, and make that:
	/usr/5bin/stty mode < /dev/ttya
Your way will _really_ set "mode" on the tty you're executing it from.

Kevin's problem was in the way he was _querying_; he should have done:
	stty -a > /dev/ttya
