Hm... So more a political thing ;-)

In my case (serial messages from many devicesincoming on one 
port)throwing away messages does not make that much sense.

At least printing a warning in the startHook()?

The subtle errors on not using a buffered connection (all messages are 
still valid, but some messages are lost) can be detected by looking at 
the ndlcom-packet-counter at runtime...
