Re: Serial console

[Christoph Plattner]

Yes, you are right, I have to apologize !

So, I have not really the semantic of this option.

Let's try with the new status of knowledge:

* GRUB only support 2 kinds of console: one is serial, the other is 
  VGA/KBD.
* While the timeout is running, all (= 2) consoles are "polled" if
  a user reaction is detected, if one is detected, then this device
  is select as console device. Correct ?
* If the timeout runs out, then the console type is used, which is given
  as parameter in the `terminal' call.

Is this the correct semantic ?

BTW: The wording of that stuff is not the best in GRUB (should not
want to cirticize here, but a suggestion for the future):

CONSOLE is the basic device a system uses to interact with the
environment.
If a system is fully up, also other terminal interfaces and network
services
(telnet, etc) can be used to interact with the machine.

A system canbe configured to a "serial console" or to a "...." (and this
is the difficult part !), for example "screen/keyboard" is often used
on UNIX machines, "VGA/keyboard" is also suitable for PC architecture.

So the call `terminal' should be named 
        console --timeout=0 vga
and/or
        console --timeout=0 serial
etc....

But again, perhaps an idea for the future.

With friendly regards
