Hi,
Just realised a problem. If you have already booted into PXELINUX etc then you
will already be past the point where F1 is still valid since the BIOS only
briefly checks for F1 before then going onto other tasks, e.g. booting an OS or
a boot loader once that has started the F1 checking has already stopped.
Therefore probably your best bet would be to put in a KVM-over-IP box which will
definately let you do this, e.g. http://www.realvnc.com/products/KVM-over-IP/
On the subject of PXELINUX it might be theorically possible to do some sort of
double boot into PXELINUX and then back to the BIOS routines. However let's
just keep that to a personal theories of mine (well with some testing) as last
time I mentioned double booting on this list it seemed to confuse several people
and right now I have other things to worry about but I do read this list with
interest.
It is also worth flagging that barcode "wedge" scanner adapters are
interesting things to play with since many of these devices convert RS232 (from
the scanner) to the keyboard TTL connector and also feature a keyboard
connector, thus you can plug in one of these adapters to a PC and connect the
other up to another PC via a null modem cable to send keyboard commands. I
sadly don't easily have mine to hand to try at the moment and never bothered
with trying to send F1 should work.... However this is a separate discussion to
PXELINUX etc.

Greetings to .HU - to do this you need a way to be able to send the following 2
bytes which represent the keyboard scan code for F1:
1st byte = 0d / 0h / NUL (null character)
2nd byte = 59d / 3Bh / semi column (;)
(see http://www.jimprice.com/jim-asc.htm for more details)
I am NOT personally not that familar with Xterm however this google search
returns several pages which should help -

Over a serial emulation provided by the BIOS, I get the PXELINUX boot
prompt all right. Now, how do I send F1 to get a help screen? It's
not PXELINUX specific, of course, F1 would also come helpful for
entering the BIOS Setup program. Its accross telnet running in an SSH
session from an UTF-8 xterm, as it probably matters. I would be
grateful for any insight.
