• XON/XOFF
In this protocol, the communication is controlled by the special
characters XON (ASCII 17 dec.) and XOFF (ASCII 19 dec.)
being transmitted on the same line as the data. XON/XOFF can
be enabled/disabled separately for data received from the host by
the printer (printer sends XON/XOFF), and for data transmitted
to the host from the printer (host sends XON/XOFF).
XOFF is sent from the printer when its receive buffer is filled by
75%, and the transmission from the host is held up awaiting an
XON character. When enough data have been processed that the
receive buffer is filled only to 50%, the printer sends an XON
character and the host resumes transmitting data. The same
principles apply to XON/XOFF sent by the host, even if the
percentage may differ.
By default, XON/XOFF is disabled for data both ways.

New Line

Selects the character(s) transmitted from the printer to specify the
switching to a new line. There are three options:
• CR/LF ASCII 13 dec. + ASCII 10 dec.
• LF ASCII 10 dec.
• CR ASCII 13 dec.

Receive Buffer

The receive buffer stores the input data received on the serial chan-
nel before processing. Default size is 300 bytes.

Transmit Buffer

The transmit buffer stores the output data received on the serial
channel before transmission. Default size is 300 bytes.
Connected Hardware ("uart2:" and "uart3:" only)
In case of an optional interface board, you can read (but not set) the
type of connected hardware as one of the following alternatives:
• RS232
• 422 non isolated
• 422 isolated
• 20 mA Current Loop
