Correct. User will have to enable debug flag of 0x1.

Yes, it will be repeated. I did add a "net_ratelimit()" to it so it
should not be too overwhelming. I did not care to limit it even more
since we are now talking about a debug message as opposed to an error
message on the console.

Sorry - will fix. I will not post a new version to this thread for this
issue, but it will be fixed in the next version I send out.
