You've got to get the serial settings set up right, and you should be
using a -current kernel (Stock 1.1 has broken serial ports). I'd recomend
a recent (1.2 beta) kernel/lpd combo as lpd now nolonger worries about
the baud rate you specify for a printer. This change matters most for
DeskWriter owners (who need 57600, which lpd didn't used to support), but
you might care, depending on the baud rate.

-current also supports setting stty-style flags for the port configuration;
no more setting and clearing flag bits. See the man page for details.

Take care,

Bill
