Configurable Protocol
Configurable protocol is based on Intermec’s Polling Mode D protocol
except that you have the option to change some of the serial port protocol
parameters or remove specific events from the protocol, such as Poll or
handshake.
You can configure the following serial port parameters:
• Baud rate
• Data bits
• Parity
• Stop bits
• Flow control
• EOM (End of Message)
• Configuration commands via serial port
• LRC
• SOM (Start of Message)
• Handshake (enabled or disabled)
• Poll (Polling) (enabled or disabled)
• Timeout Delay
Configurable protocol uses EOM to determine one of the following serial
communications modes:
Character Mode
When EOM is disabled, the terminal communicates in Character mode
processing each character. Character mode supports both XON/XOFF
and CTS/RTS flow control.
Frame Mode
When EOM is enabled, the terminal communicates in Frame mode.
When a terminal sends a packet, it adds protocol character. When a
terminal receives a packet, it strips any protocol characters before it sends
the information to the terminal application. Frame mode supports both
XON/XOFF and CTS/RTS flow control. In Frame mode, you can also
define these serial port parameters:
• Configuration commands via serial port
• Handshake
