Description
Serial interface standard.
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.
Note
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.
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.
