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.
