The other day someone brought me an old Apple Laserwriter II with a serial

interface set at 57600 baud, and I found out the hard way that lpd doesn't
know about speeds greater than 38400, even though <sys/ttydev.h> also
permits 57600 and 115200 baud. Fix this by adding B57600 and B115200 to the
'bauds' table. (The Apple printer worked properly once I did this, BTW. :)
