Property Name
Description
Baud Rate
The rate of signals transmitted per second. The larger the number,
the faster the data transmission.
Data Length
The length of the data transmitted. It can be set to
7
or
8
bits.
Parity
It can be set to
Odd
,
Even
or
None
. A parity bit is added to a string
of data bits to check if the data is correct.
Odd
The total number of “ones” in the data plus the parity bit is an
odd number.
Even
The total number of “ones” in the data plus parity bit is an
even number.
None
No parity check is used.
Stop Bit
The stop bit is at the end of a string of data bits. It is used in
asynchronous transmission to let the receiver know that the string of
data bits being transmitted is end.
Flow Control
Flow control is used to control the data flow between the computer
and your printer.
XON/XOFF (DC1/DC3)
It is software flow control that uses control
characters to handle data transmission. When your printer is unable
to process the data the computer send, it sends an XOFF signal to
tell the computer to stop sending data; once your printer is able to
accept data, it sends an XON signal to notify the computer to
resume sending data.
RTS
It is hardware flow control that uses dedicated wires to handle
data transmission. when the computer is ready to send data to your
printer, it sends a Request to Send (RTS) signal to your printer. If
your printer is able to accept the data, it sends a Clear to Send
(CTS) signal to the computer. That is, the computer starts sending
data when it sees CTS on; it stops sending when it sees CTS off.
