About serial communication settings
Each serial device is controlled by a series of communication
characteristics that define the low-level communications
with the printer.
When you configure a new printer,
the default values should be sufficient for most purposes.
The serial communication parameters are:
BAUD-
Speed of the serial connection.
The default speed is 9600bps.
Parity-
The system uses parity for error checking. By default,
this field is set to None.
Stop Bits-
By default, this field is set to 1.
Character Size-
Number of bits (7 or 8) per character.
Character size is set to 8 bits by default
(not to be confused with font size,
which is the size of a printed character in points).
To change these parameters, see
``Adding, modifying, or copying a local printer''.
You can configure additional serial line characteristics using
lpadmin(1M)
or by editing the print interface file
(in the /usr/spool/lp/model directory) directly.
See
``Creating printer interface scripts''.
stty(1)
summarizes the various characteristics
that can be set on a terminal or printer port;
however, not all of the characteristics listed in
stty(1)
are important for printers.
