How to send Fn (F1,F2) over Serial console theu PuTTY


Hi people,

I'm kinda new to Linux over serial console and I'm doing the following setup

ASUS KFSN4 DRE/SAS MoBo (BIOS setup to redirect after POST)
XEN Dom0 Kernel
CentOS 6

I have a null-modem serial cable connected between two Linux servers and it works flawlesly, I connect to the serial console of server 2 through Server one using

Code:
screen /dev/ttyS0 115200
Serial Console works, but I do the following to reach it as it's on a remote location

PuTTY -> Server 1 -> screen / minicom to server 2

What I want is to be able to use the BIOS setup remotelly, when mobo is POSTing it sasy

Code:
Press DEL to enter BIOS SETUP (Pres F4 on remote Keyboard)
And I press it using either screen or minicom and it doesn't work, I can't reach the BIOS setup utility.

Any way to pass these keys with either of this apps or any advise.

Thank you.

I am willing to bet you can't use any pre-OS remotely without a very special remote card and software.

If you didn't finish POST and load the OS then how can you connect remotely? Think about it.


Intel used to make a specialized remote card sort of a nic card and may still along with others for that feature.

Thank you very very much for the time you took to answer, also There is no need for such thing when you have remote console, altho it's very old, slow and not very functional, but for the purpose of my research and what I do with XEN it's enough because when I chanhge network settings I can loose connectivity, and to fiddle with BIOS settings.

And what you're talking about is a management card and that's even more powerful TCP/IP access, web interface, and such things.

And, Well, I found out that changing the "The function keys and keypad" I switched from ESC[n~ to VT100+ and now it sends the correct escape sequences and I can access the BIOS using the described setup and connect with

Code:
 screen /dev/ttyS0 115200 or minicom
Thank you again.
