• Message type: This parameter indicates how incoming text will be parsed to build
messages. In order to match most existing protocol, two different incoming message types
are handled.
• Fixed length messages: All messages are always expected to be the same length. The
user has to provide the message length parameter.
• End of message character: All messages are expected to have a special "magic"
character to indicate the end of message. This type matches most text-based protocol
with an end of line character (\n) to validate the entry. You have to provide the end of
message "magic" character. Multiple character sequence is not supported (e.g., \r\n).
Note that the "magic" character will NOT be part of the message sent to the playback
engine.
• Save the new configuration.
