Annoying "zs0: parity error ignored" message from tty port with modem

[Rob Bernardo]

I am running SUN OS 4.1 and have a Telebit T2500 modem connected on one of
my tty ports. Every time the modem hangs up, I get the benign (?) but
annoying message "vmunix: zs0: parity error ignored".

Is there some parameter somewhere I can change so that parity isn't just
ignored but not even noted enough to produce this message?
