Dear Sun managers,

I'd like to ask a question about console i/o. Basically I'd like to have
multiple ways to get to the console.

I have these options to connect to console,
- RSC (tcp/ip or serial)
- ttya serial port connection
- attached keyboard and monitor

I understand ttya input/output or setenv commands can change the i/o while
I'm in ok prompt. But it seems there's only one access allowed for the
console, and therefore the above methods are mutually exclusive. Is this
true?

Also, if they are mutually exclusive, is it possible to redirect console
i/o, for example from serial connection to locally attached keyboard and
monitor, while the system is up and running?

Thanks.
