Re: How to disable console on serial when needed ?

Can't you just use remote syslog for this? It's the way I do.

Good Idea

However can it handle user program's printf output ?

You could replace the printf statements to send syslog request instead, but
you could also write a simple "wrapper" script that simply writes it input
into syslog. I don't know if "logger" is sufficient. If not, you can take a
wrapper which simply calls for logger. I don't know if you have it, but it
is at least available through BusyBox.

And Is there any document on this ?

Only the BusyBox documentation. :-)

And anyway, it need a network to working on right?

Everything syslog is logging, is going to /var/log/messages (but you can
configure syslog accordingly to your needs in /etc/syslogd.conf - BusyBox'
syslogd can't), but this is also sent out to the network, if you want it to
do so.

So - yes, you need a network to be able to get these messages, if you are
not having a terminal to the system.
