Communication
Setup, cont'd.
Note:
It is note recommended that yoy
enable XON/XOFF, Data to
Host.
In the setup string examples,
underscored space characters
(as in "DATA_TO_HOST") in-
dicate mandatory space charac-
ters in the command line.
Quotation marks (" ") are ASCII

• Data Flow Control
Data flow control determines serial communication between
printer and host. It prevents characters being lost when data is
transferred between printer and host at high speeds over the
RS232 serial port. It is important that the printer and host have the
same configuration.
There are three recommended settings for controlling data flow
between printer and host.
- No flow control
RTS/CTS is disabled
XON/XOFF, Data from Host is disabled.
XON/XOFF, Data to Host is disabled
- RTS/CTS
This protocol controls communication by handshake signals
through separate wires in the cable.
RTS/CTS is enabled
XON/XOFF, Data from Host is disabled.
XON/XOFF, Data to Host is disabled
- XON/XOFF, Data from Host
This protocol controls communication using the special char-
acters XON (ASCII 17 dec.) and XOFF (ASCII 19 dec.) which
are transmitted on the same wires as the data.
RTS/CTS is disabled
XON/XOFF, Data from Host is enabled
XON/XOFF, Data to Host is disabled
Setup strings, examples:
SETUP "SER-COM,UART1,FLOWCONTROL,RTS/CTS,DISABLE" ↵
SETUP "SER-COM,UART1,FLOWCONTROL,XON/XOFF,DATA_TO_HOST,DISABLE" ↵
SETUP "SER-COM,UART1,FLOWCONTROL,XON/OFF,DATA_FROM_HOST,ENABLE" ↵
• New Line Character
This setting specifies the character(s) transmitted from printer to
host to initiate switching to a new line:
- CR
- LF
- CR/LF
Setup string, example:
SETUP "SER-COM,UART1,NEW_LINE,CR/LF" ↵
