4. Flow Control ON Buffer Level
Once the Flow Control OFF buffer level has been reached, the
“no-input accepted” mode will continue until the EtherPoll has
transmitted enough data to reduce the buffer contents to this
point.
5. Line_Terminator_Character
This setting is used to change the Line Terminator Character.
The Line Terminator Character causes any data in the buffer to
be transmitted immediately when the character is received,
provided the following setting (Transmit_on_LT_Char) is ON.
6. Transmit_on_LT_Char
When this setting is ON, any data in the buffer will be sent
immediately upon receipt of a Line_Terminator_Character (see
previous setting). When the setting is OFF, the
Line_Terminator_Character has no effect.
This is usually set OFF for SCADA applications.
7. Transmit Mode Filter
This setting can turn the filter function ON or OFF.
If ON, then when a CR/LF (Carriage Return, Line Feed)
character pair is received, it is converted to a CR only before it
is sent to the serial port output. CR/LF pairs are normally used
in the MS-DOS environment to mark the end of a line, but may
cause problems in other environments.
CR/NULL character pairs are also converted to a CR only. If
this setting is OFF, then no conversion is done.
This is usually set OFF for SCADA applications
