Speed at which data is transferred.

Baud rate

translates approximately to

bits per

second

The serial port

Baud Rate

setting must

match the host computer baud rate
setting.

Your software application may set the
baud rate. If not, use the DOS MODE
command to modify the baud rate on
the host computer. Refer to your DOS

documentation for more information.

Handshake

Robust XON*

XON
Hardware

Data flow control. (Flow control, also known as
handshaking, is the cooperation between the host
computer and printer for data transfer. XON signals
the host computer to send more data. XOFF is the
converse signal that tells the host computer to stop
and wait.)

Robust XON

sends the XON signal continuously.

Robust XON

helps ensure that handshaking works

with a host computer that fails to receive the XON
signal.

XON

sends the signal only once.

Hardware

is used when the host computer cannot

operate in XON/XOFF handshaking mode.

Hardware

requires a cable with the DTR (Data Terminal
Ready) pin connection enabled

DTR Polarity

High*

Low

Serial port’s DTR (Data Terminal Ready) signal sent
from the printer to notify the host computer that it is
ready to receive data.

High

is standard for most computers; it uses true logic

(+5 V).

Low

is typically used on nonstandard equipment; it

uses inverted logic (0 V).
