Hello U-booters,
This is a quick one: is the network console mechanism bidirectional?
In other words, can I have a full-fledged network-based console or is the ncb facility only enough to receive bootup messages, but not able to send them ? I am not quite clear on that from the dox...

In U-Boot, yes.

Really? What is not clear about "... network input/output devices by adjusting the 'stdin' and'stdout' environment variables" ??
You did read doc/README.NetConsole, didn't you? :-(
Best regards,
Wolfgang Denk

ncb is able to receive only - use the standard netcat utility (nc) to send keyboard data to u-boot.
Note - the use of ncb is only necessary if u-boot is configured to send its data as broadcasts. If ncip is defined then use nc both ways.
