Open ports on TriCaster that can be disabled

Port 7 is the Echo Protocol which is used for general network testing and measurement

Port 13 is Daytime Protocol which returns an ASCII string of date and time and is also used for network testing and measurement.

Port 19 is Character Generator Protocol, yet again another device for testing and measurement.

None of these services are used by TriCaster or NDI and can be disabled if desired.
