The constant “system configuration data output”is used to specify the output of the
system configuration data.

Sends the message and receives the response. This member adds a terminator to
the message and sends it.

Designation of System Configuration Output Format
sendLineDARWIN(comm, "CF0"
Sends the CF0 communication function command (specify the module information
that has been configured for the system). This member adds a terminator to the
