I pulled my hair out for a week over this problem.

The purported 4.0.1 fix didn't work for me (Sun3/260, Citoh3500 on ttya).

Sun *DOES* have the answer!  I called the hotline, a software engineer,
Ray Jang (I think) sent me a 4.0.1.a patch tape.  This tape had fixes for
the serial tty driver in the kernel.  The printer works perfectly.
