Syslinux - Aug 2007 - Redirect on both VGA and serial?

Dear List

maybe a simple question. We have a pxelinx server in our network which only sent
the output on a serial console. Now we want both output on VGA and serial
console. I think pxelinux redirect the output default on VGA. So I think the
only changes I have made is to add "tty0" into the "label"
section in the "default" file. Is this correct?

Mit freundlichem Gru? / Best regards

Are you really refering to the (pxelinux) server which could be anything you are
able to install a DHCP and a TFTP
server on, or are you actually refering to the "config" files
(pxelinux.cfg/...) stored on the server which
control the clients' behavior.

In the later case it would be helpful, if you would send (the significant part)
of your
config file(s) and furthermore tell the list which version of pxelinux you are
using.
Still assuming we are in the "later case" I guess that there is a
"SERAIL port ..."
statement at the very beginning of your config files which
<quote>
  "Enables a serial port to act as the console"
</quote>
and possibly a "CONSOLE ..." statement.

See

and

for details.

What you're talking about is actually the kernel, not pxelinux.

For the kernel, to get output on both you would have to do put
"console=tty0 console=ttyS0" as part of your "append"
statement.

Now, a subtlety is that user space (as opposed to kernel) output will
only be sent to the last thing listed on the command line.  You can't
get that sent to two places.
