Yes, I've done that, in ~/.config/mpv/mpv.conf [1]

  audio-channels=stereo

that makes me wonder, what happens if one has that _and_
downmixes as suggested? [last] is a/the zsh downmix
wrapper around ffmpeg, that has worked to some extent.

But, not to all extent :(

Today I got this [3], checking with mm-audio [same file as
mm-downmix below, line 20] as I always do since
I learned of the 2 or 5.1 (6) channels, it reports

  $ mm-audio blade-runner-2049.avi
  blade-runner-2049.avi: Stream #0:1: Audio: ac3 ([0]
  [0][0] / 0x2000), 48000 Hz, 5.1(side), fltp, 384 kb/s
  6: L R C LFE Ls Rs

unfortunately

  $ mm-downmix
  Could not write header for output file #0 (incorrect codec parameters ?): 
Operation not permitted
  Error initializing output stream 0:1 -- 
  Conversion failed!

with

  $ file blade-runner-2049.avi
  blade-runner-2049.avi: RIFF (little-endian) data, AVI,
  720 x 304, 23.98 fps, video: XviD, audio: Dolby AC3 (6
  channels, 48000 Hz)

So I think it is the avi file format that it/something
cannot handle?

In this file, the speech is so weak and the wrestling,
arguing, and shooting (or whatever on Earth they are
doing) so strong, putting bass to -5 and trebl to +5 on
the stereo and turning down the volume in mpv still
doesn't do it, it's too loud when shooting while barely
audible when talking.

I'm starting to think, can this be my ears? :O Or is
this a common situation?

Feel free to get the file and tell me, that'd be much
appreciated...

But apart from that, what can one do to downmix avi
files, if that is indeed what causes the sudden
malfunction of the command?


#! /bin/zsh

# https://dataswamp.org/~incal/conf/.zsh/audio-norm

mm-downmix () {
local files=($@)

local name
local ext
local out
for f in $files; do

The mode you appear to be describing is selected in the BIOS on this
Lenovo laptop, where it's described as HotKey Mode. When enabled, the
✈F7 key, for example, will put the Wireless into airplane mode, and you
need to hold down Fn to get the real F7 function. I disable HotKey Mode,
so that you have to hold down Fn to get ✈.

Cheers,
David.

Some sort of server is a good idea. It need not be the latest and

Should you desire to know the expected output from inxi -Gxx, and share it, the
inxi author has implemented a tentative fix to the recently discovered 6 year 
old
problem. This is his instruction:

cd /usr/local/bin && wget -O pinxi smxi.org/pinxi && chmod +x pinxi

Probably this requires a root login to correctly execute. pinxi is the beta
version of inxi, so your test would be:

pinxi -Gxx

The author is likely interested to see your result should you proceed.

https://github.com/smxi/inxi/issues/214 is the relevant bug report about this.

Re: Exim4 et paniclog

[Ludovic]

Bonjour G2PC,

    plusieurs axes de recherche:

1) Il faut débuger ton script shell

echo "Connexion au terminal du serveur le `date` `who`" | mail -s "Accès au Shell du Serveur `hostname` 
par `who` depuis `who | cut -d"(" -f2 | cut -d")" -f1`"m...@moderateur.com

Visiblement ce script ne fonctionne pas toujours, plutôt qu'envoyer un 
mail tu peux rediriger vers un fichier, puis regarder son contenu. Tu 
peux aussi vérifier les variables d'environnement définies à ce moment 
(env >> ). Ton script shell alterne beaucoup de 
double quotes et de simple quote, c'est facile de se tromper... Tu peux 
avantageusement remplacer un `date` par $(date), ce sera moins source 
d'erreur.


2) La commande who te renvoit la **liste** de toutes les personnes 
connectées, à ta première connexion, elle pourrait renvoyer une seule 
ligne, et à la seconde renvoyer deux lignes. Avec who renvoyant 
plusieurs lignes, ton script n'est pas robuste...


3) Tu peux vérifier que ta configuration mail fonctionne correctement en 
faisant des tests d'envoi avec la commande mail et en surveillant les 
logs exim


4) Ton but semble être d'envoyer un mail pour toute connexion SSH, dans 
ce cas une bonne solution est d'utiliser /etc/ssh/sshrc, cf [1] et man 
sshd. C'est ce que j'utilise pour monitorer les connexions SSH externes.

VDH can't download videos from several sites as one file, because they

Laptop with 2 external monitors

[Sylvain Archenault]

Hi,

I'm have a laptop with Intel HD 620 graphic card and i'm trying to set
it up with 2 external monitors. So i have a usb-c hub where i connect
the first monitor with HDMI and the second one with DP. I'm able to have
both of them work with the following resolutions:
- 1920x1080 : internal display
- 1920x1080 @ 60Hz : hdmi display)
- 1920x1200 : DP display

Having said that the DP monitor can go up to 2560x1440 but I'm unable to
use that resolution with the order monitor active. I only see this in
the log:

/usr/libexec/gdm-x-session[1069250]: (EE) modeset(0): failed to set
mode: Invalid argument

Based on
https://www.intel.com/content/www/us/en/support/articles/25675/graphics-drivers.html
I thought it would be possible to use the highest resolution.

If I disable the HDMI display, I can go up to the max resolution.

Is there something i'm missing? or somewhere I could look to confirm my
graphic card/system doesn't support the configuration I'm trying to do?

Thanks

All I can say is that it /can/ download the video the OP wanted.
It can also download videos from sites that youtube-dl reports as

It's polite, when posting a link to a site that may contain porn, to
indicate that the site is "NSFW" (not safe for work), so that people who
are in a position where viewing porn could be a problem will know not
to open that link.

I think you've been answered, but let me try the usual thing of
answering a different question.

Do you really need Thunar as root very often? I very occasionally use
Nautilus as root, so I don't mind the extra step. I'm careful to close
it immediately I've finished the job, I would be scared to leave a root
file manager open that looked exactly like my normal file manager. And
this is on a sid workstation, which is expendable.

I do almost all root work in mc, in a terminal window. There are only a
few things that a file GUI makes easier, and mc contains a simple text
editor and quite a few useful shortcuts. My server doesn't have X, so
it's mc by default there. 

But the main reason is that I find it easier to remember I'm in a risky
environment when I'm using mc. I'm just automatically much more
cautious. Maybe it's distant memories of Norton Commander on DOS...

I actually tried that myself a little bit ago. It didn't work. The
reason I thought to try it is that I *have* had that work for
something in the past. I'm guessing it maybe worked on either a
different Debian release or different Linux distribution entirely..

That ALT+F1, F2... I stopped doing that only with this Dell Inspiron
Duo laptop I'm on. Takes too much coordination of my fingertips
because I have to (keep remembering to) hit Fn+ALT+F2 for it to
function.

It seems like there's a toggle switch somewhere that triggered a "Hey,
wonder what THAT CHOICE does when you click it?" moment. Whatever that
option is, what it (apparently) does is make you have to toss in that
Fn key on regular occasions that you don't use it for on other
keyboards...

This is inxi output unlike any I have ever seen.

driver: i915 v: kernel

is normal and expected, a result of using the i915 kernel module.

X.Org 1.20.7 driver: i915 compositor

is unexpected. i915 is not an X graphics driver. Compositor is normally on the
next line. Normally one would expect that output to resemble this:

X.Org 1.20.7 driver: modesetting unloaded: fbdev,vesa alternate: intel

Of course, these are for systems with only one GPU. Your laptop has dual GPUs, 
so
there should be a Device-2, which is missing from inxi output

Apparently prime is in use to manage GPU use. As I have no experience with 
laptops
with dual graphics, and thus none with using prime, and neither with 
DisplayLink,
there is probably no more assistance for me to attempt here.

You can create a custom .desktop file by using "exo-desktop-item-edit"
[1] utility:
       $ exo-desktop-item-edit --create-new -t Application --name
"Hazardous Thunar" --comment "Open Thunar with elevated rights"
--command "pkexec /usr/bin/thunar" --icon "Thunar" ~/Desktop/
This command will create application file named "Hazardous Thunar" on
your Desktop.
You can create a new item for your application panel [2], using Launcher
plugin, in the same manner.
gksu\gksudo is now deprecated, so you have to use "pkexec" to launch
files as root with GUI dialog. Fortunately Thunar already comes with
polkit [3] action file, so you don't have to make a custom one.

Bonjour,

À l'époque de Debian 6, j'ai un vague souvenir d'avoir eu à
un moment à mettre à jour la pile logicielle freerdp dont se
sert Remmina pour accèder aux machines Windows.  Les versions de
protocoles supportées par le freerdp de l'époque étaient trop
anciennes par rapport à celles configurées comme acceptables par
le serveur RDP.

Je n'ai pas eu l'usage de RDP depuis, donc je ne saurais pas
dire si c'est le genre de problème auquel vous êtes confronté.
De plus, je ne suis jamais passé par une page web pour me
raccorder à un serveur RDP, donc peut-être que je fais
entièrement fausse route.

Amicalement,

You could press Alt-F2 and enter sudo thunar.
Since I don't use sudo, I can't test if it works. But I can see no

I'm not sure what the implications are of having to login to a site.
But in general you need different tools for different web sites.
The BBC iplayer and youtube-dl are two such tools, and sometimes
a download link is even available, which either the browser or
wget can use (the latter preserving the metadata).

Where videos exist in their entirety, some sites still play them
by downloading to a temporary file (and you can see the
download in the progress bar, ahead of what's actually playing.
A technique there is to examine /proc/N/fd where N is the
process number of the browser tab. (The process name used to
be xul-runner, Web Content etc, and looks as if it's currently
/usr/lib/firefox-esr/firefox-esr -contentproc.)
If you find an fd number F that's pointing to a file (deleted) in
/tmp, then try copying that /proc/N/fd/F (following links). Do it
when the download progress bar has reached the end, but the file
is still playing. (Sometimes everything disappears as soon as the
end is reached.)

Another technique is where the source is streaming (and might be
open-ended). Here, the video can end up as fragments in your
browser cache. How you handle them depends on whether they are
audiovisual or in two seperate streams, and whether they are
timestamped. Some are, some aren't. The former are relatively
easy to reassemble with ffprobe to read the timings and ffmpeg
to concatenate the pieces (and merge audio/video if necessary).

Where there's no internal timestamping, you can sometimes rely
on the filesystem's own to figure out the correct ordering.
But I prefer to run a script that watches files in the cache
as they are closed (with inotifywait), and immediately copies
them out (if the filetype is of interest) with a sequence
number and the file type in the filename. The relevant segments
can then be concatenated quite easily. A timeformat of
%Y%m%d-%H%M%S works well as a more meaningful sequence number,
particularly if you append %N to include nanoseconds for the
necessary time resolution.

Be aware that the fragments in your cache might not all be
identified by the file program's defaults. For example, I use
0   string  G@  TS transport stream
in ~/.magic to pickup files that file might otherwise label
as 'data'.

Sometimes, even then, you have to use a little ingenuity for
the quiet life: eg there's a UK railway site that has three
webcams (two stations and the yard) which run simultaneously
on the same web page. Fortunately, each webcam runs with a
different frame speed, so it's quick and easy to distinguish
their files and divide them up.

Finally, when all else fails, and if you've read this far,
you can just capture the screen contents with ffmpeg's
x11grab and record it to an mpg file. The disadvantages are
that you capture extraneous screen decorations, and you've got
to dedicate the whole screen to watching the video, remembering
to increase your blanking timeout too. If you can only record
audio through the microphone, you get more extraneous rubbish
there too.

Cheers,
David.

No issue at all. I was just wondering if there was another way.  In another
distro, I press Ctrl+Alt+Space and type 'gksu filemanager' and type my
password, that's it.  I find it much easier. Plus there's no terminal open
in the background.

But like I said, not a big deal. Just asking if there's another way besides
opening terminal and typing 'sudo thunar' then password.

That's all.

At this point, it's pretty clear the file system is mounted without
exec permission, so just fix the mount options.

Remember that "users" implies "noexec", too.  If you want to keep "users",
you should add "exec" explicitly.

Linux Microsoft Remote Desktop et Workspace

[David Pinson]

Bonjour,

Confinement obligé, de plus en plus de travail se font à distance.
Les administrateurs ont mis en place la connexion RDP via le web.
Mais apparemment, les PC Windows et Mac ont cette possibilité mais pas
pour Linux.

Je sais qu'il existe d'autres outils comme NX et autres, mais je dois
rester dans le protocole RDP, hélas !

J'ai regardé avec Remmina mais malgré les différents réglages, il n'y
rien à faire, impossible de se connecter à la workspace.

Avec l'outil pour le MAC (Microsoft Remote Desktop), il suffisait de
créer un lien workspace comme: https://adressesite/rdweb/feed/webfeed.aspx

Qui aurait d'autres pistes ?

Merci pour vos idées et aides,

-- 
Linuxement vôtre,

Hello Friends!

I was just wondering if there are  easier ways to open Thunar file manager

Right now what I do is this:

Open xfce4-terminal,
Execute:  sudo thunar
Type my password.

Not a big deal but if there is an easier way I'd like to know.

All I can say is that it /can/ download the video the OP wanted.
It can also download videos from sites that youtube-dl reports as
'unsupported'.  For me it has become a useful tool.

Ok, thanks! It would be very interesting if it has a built-in encryption

Although this of course is independent. You can have a sync directory of 
only encrypted files - it's up to you.



I do Not sync any active working data. It is first copied to the sync

syncthing provides zero storage. It is a transfer/sync tool between 
separate hardware.

the "cloud" is user owned and controlled.


That's what I understood about Syncthing.
The data is *distributed* between the devices and not on a central 
server somewhere (like Nextcloud). It's a decentralized!

I think that's the main difference between Syncthing and Nextcloud ?


separate use, it was a sidebar comment. I only use them for small 
specific purposes as needed.

Dropbox is easy to use for sharing with others.
Mega syncs photos and files between my Androids and my computers 
gracefully, then I copy data to my system.


So, let me suggest something too (if you have the resources for one more 
machine).
Try to use Nextcloud for this use, so your data will never remain in the 
hands of others - other than yourself and those who want to send it.

I could have done a better job of frasing my question as
I love the power of unix and use shell scripts and aliases
all the time.

What is confusing me about scripts in microcom is the
following situation:

I wanted to output device-specific commands and at least
see the responses much like the send/expect pairs in the expect
utility or the OUTPUT and INPUT commands in kermit scripts.

One starts the script while in the command mode of
microcom and it seems that your script should only contain
commands for microcom such as defining the port, speed, etc,
basically what the help screen says one can do.

It doesn't seem like you can put device-specific commands
in the script file.

I wrote a little script that exited command mode with the
exit command and then typed a command that was meant for the
device and then I typed x ./tester while in command mode.

It ran the "exit" command which put one in the terminal
window.  You could type things then and each thing you type went
right to the device.  I then removed the exit command and left a
command for the device.

It interpreted that command as being meant for microcom
so did not do anything but respond that it did not understand the
command.

microcom does work with expect but can't see the Carriage
Returns at the end of the lines returned by the device.  If you
know how the response should end, expect does see the ASCII
characters and moves on.  Otherwise, one must allow a reasonable
time such as 1 second for the timeout.

I was hoping there was some way to duplicate expect or
kermit with just the microcom app but this is not a show stopper
at all.  At least there is still a serial terminal that can talk
to devices whose only connection to the outside world is a RS-232
cable.

Again, thanks for everybody's help.

They're not 'old-school', they're badly designed. The spec says,
unequivocally, plus and minus 3V-15V and has done for a great many
years.

The 'logic' level data, quite common these days, is RS-422 or
RS-485. It should not ever be compatible with RS-232. Most serial data
originates at logic level (anything from 2.8V to 5V) and ends up at
logic level somewhere else, so there is little point in converting to
and from RS-232. But things like radio modules often run on 3.3V or
lower, so it may be necessary to convert to and from RS-422 levels.

Many modern 'RS-232' devices, particularly the really cheap USB-serial
modules, in fact use 3.3V/0V or 5V/0V logic levels, as the term 'RS-232'
has just come to mean 'low-speed serial' to many people.

Hi Felix and Greg, Thank you so much!

Here is more information.

I'm try to got 3 monitors in my debian bullseye. In this days/ weeks,
months, I have googled a lot to find any rule to tell me how I could to
put my third monitor to work. It is plugged in a DisplayLink FY
USB-DVI in this manner:

notebook usb3.0 port -> cable -> DisplayLink FY USB-DVI -> DVItoVGA
Adapter -> VGA cable -> Monitor AOC 511vw

I try this with the this instructions https://is.gd/Ijp1k1 and with the
DisplyLink install script (https://git.io/JvADQ). Not success.

So, I read in some place that can be a possible conflict with xorg
module. To figure out the solution, I'm try to uninstall all
unnecessary module. I'm in this point/step now.

That command only shows one of your cards, and not the other.  It's
simply not a command that gives you much useful information in this
situation.

> What xorg package I can uninstall?

What on earth makes you think you need to REMOVE software in order to get
the results you desire?

What even makes you think you're not already using the AMD card?

You need to check your X or Wayland logs before doing anything else.
Maybe you're already using the card and driver that you want to use.

If it turns out that you're not using the desired card, then there are
a few things you can look into next:

1) lspci -nn

Don't try to grep it or anything, because one of the cards doesn't show
up with the characters "VGA" in its output.  Just post both of the lines
from this command, one for each card, which will give us the PCI ID
to identify the hardware.

2) dmesg | grep -i firmware

See if the kernel is trying to load any firmware and failing.  If so,
you will probably want to install some of the non-free firmware packages
to support your hardware.  This may involve adding contrib and non-free
to your sources.list.

3) Google your PCI ID together with keywords like "debian" to see if there
   are any success stories for using your hardware on Debian.

Usually you are not the first person to attempt something.  Learn from
those who came before.

What is output from:

What type cable is connected to which physical connector on the PC?

What is the Dell BIOS setting for video?

> What xorg package I can uninstall?

You can probably uninstall all of them and still be fine. Most likely the only
ones to keep would be xserver-xorg-video-amdgpu (probable preference) and
xserver-xorg-video-vesa (for rescue purposes). The intel doesn't require
xserver-xorg-video-intel, as it usually works as well or better with the only 
DDX
you don't see installed, modesetting, since as default it's not in a separate 
package.

Judging from the source it it should open a text file on your side (i.e.

So whatever you'll write in the file is specific to the device you're

Time to learn the awesome power of Linux.

Three ways to do this:

1. shell script

Create a text file with the following two lines of code:

#!/bin/sh
exec microcom -f -p/dev/ttyUSB4 -s9600

Name it something short and memorable, like serial

Then

chmod a+rx serial

And from then on, it's a program you can run.

2. shell alias

Most shells have aliases available. In bash, you can stick them
in your .bashrc file. Add this line:

alias serial='microcom -f -p/dev/ttyUSB4 -s9600'

and then re-evaluate your .bashrc (which is done automatically
on login):

. .bashrc

Now you have a new command.

3. shell function

Most shells have functions available, too. The difference
between an alias and a function is that an alias is just a
substitution, but a function can take arguments and perform
complicated feats of logic. In this case, a function is
overkill, but it's still easy to drop in to your .bashrc.

function serial {
microcom -f -p/dev/ttyUSB4 -s9600 
}


There you go.

Another possible fly in the ointment could be a hardware
issue.  Some RS-232 ports are old-school and aren't happy with
any voltage range other than +12 for one state and -12 for the
other while there are serial ports that can handle state changes
of + or - 3 volts so they safely handle logic-level signals and
also can handle the old-school RS-232 levels.  Then there are
some that handle logic-level signals and would figuratively melt
if you hit them with +-12 volts.

Microcom; What's this Script Feature?

[Martin McCormick]

While working with Microcom, I tried the "help" feature while in
command mode and it works but there doesn't seem to be much other
information.  Here is a screen shot of a command I sent to a
serially-connected two-way radio followed by the Help screen for
microcom:  I put a * in front of the script command.


connected to /dev/ttyUSB4
Escape character: Ctrl-\
Type the escape character to get to the prompt.

Everything seems to work as far as I can tell but what
does a script look like?

I am sure it's kind of like expect or the old kermit
scripts but I haven't yet been able to send anything it liked.

The system I have been hacking on sends only carriage
returns in it's responses so what one gets on the screen is one
long line that gets over-written but that's no mystery.

The unix convention of typing the Up-Arrow and starting
microcom is very handy since one does not have to type

microcom -f -p/dev/ttyUSB4 -s9600
each time.  Actually, I usually get away with !mic followed by
Enter and it starts.  Good work to everybody who created this
useful little terminal program.

It's 32bit and outdated. 

Debian Buster usually installs 64bit Packages. Though 32bit can be
installed, but aren't by default.

To find out, if the filter works: can you execute it?

Ne fonctionne pas, j'ai aussi cherché de ce côté. Visiblement, c'est
une limitation du logiciel. Je vais donc sortir la vidéo à part, les
deux fois trois pistes audio et remettre le tout d'équerre avec ffmpeg
comme ceci :

ffmpeg -i video -i audio1 -i audio2 -i audio3 \

tout au logiciel utilisé mais:

- si tu paramètres 6 voies (canaux) en sortie et que Cinerella te "rend"
(une sorte d'aperçu avant enregistrement réel dans un format de sortie?)
ça en 2 voies, c'est qu'il effectue un downmixing 6->2 (6 voies en

tu as choisi un format de sortie (conteneur et codecs) qui ne permet pas
autre chose
- par exemple si tu veux faire un DVD trilingue et ça semblerait
consister en 3 chapitres dans la table des matières: quand tu veux lire
ton DVD en langue N°2, tu lances la lecture du chapitre 2, en gros. Donc
ça nécessiterait d'avoir un logiciel d'enregistrement/montage qui te
permette, lorsqu'utilisé correctement, de créer des chapitres. Et  plus
tard un logiciel de lecture qui comprenne les chapitres.
- à la lecture de
http://heroinewarrior.com/cinelerra/cinelerra.html#SUPPORTED-FILE-FORMATS j'ai
plus ou moins l'impression que ce que tu veux faire t'impose la création
d'un DVD si tu veux utiliser Cinerella (je peux me tromper)

Donc peut-être quelque chose comme ça en termes d'organisation de projet
dans Cinerella:
- format DVD
- 1 piste de video pure (si tu n'as pas de besoins particuliers)
- 6 pistes d'audio pure (canaux gauche et droit pour chacune des 3 langues)
- 2 canaux audio
- 3 chapitres, 1 pour chaque langue, avec vidéo et stéréo langue concernée

Ou alors si tu veux plus simple tu peux peut-être te résoudre à avoir
plusieurs conteneurs, donc basiquement mettre à dispo des utilisateurs
non pas 1 média (vidéo trilingue) mais 3 médias (vidéo langue 1, vidéo
langue 2, vidéo langue 3) dans des formats de sortie moins contraignants
à gérer.

D'autres que moi, plus au courant, pourraient peut-être aussi mieux te

type de contenu sur quel type de support/format de diffusion)

Exactly. There are those packages I care deeply about, so much so that
I follow development news. Those I compile off-repository, usually at
the bleeding edge; I keep whatever build infrastructure it takes well
oiled (because I do that often).

But I can't "care deeply" about each of the ~2k packages delving in
my box. I wouldn't have the bandwidth for that.

Thus, there's that other 99.95% (yeah, this statistic is probably made
up) infrastructure, which I know very little about, and which Just
Works (TM) thanks to the dedication of Debian packagers. They do an
outstanding job, and I'm infinitely thankful to them.

Thing is, "those packages you care deeply about" are different ones
from person to person. To me, it's Emacs and Guile, to you it's Apache
or LibreOffice or Lua and Enigma.

The cool thing about a distribution like Debian is that it sets
a baseline of "reasonable" versions, offering a path to deliver the
achievement of specialists to all the others. It's the glue holding
together all those brilliant gems into a coherent whole. Smaug,
if you like :)

For that, I say "THANK YOU" to all those maintainers.

In most cases any optimization gains are offset by the maintenance 
burden, e.g. you have to keep track of security updates, rebuild the 
package, etc.

In the meantime package users just 'apt update && apt upgrade' (or 
enable unattended-upgrades) and get on with their work / life :)

As far as I understand Gitlab is very complex, depends on (lots of?) 
other software that is also not packaged and doesn't have a long term 
support branch. All of these make it very difficult to create the 
package *and* maintain it in a stable release.

Hopefully at some point the upstream maintainers will adopt the long 
term support release model, as many other projects have done (e.g. 
Firefox).

Kind regards,
Andrei

Debian Developers can also choose to not package a low quality module 
(though probably many more are not packaged simply due to lack of 
manpower / need / interest / etc.).

My crystal ball is clouded this morning.

How about showing the error messages and the script?

It Works For Me.

I had a very simple serial requirement recently, and this did the job.

Oh, as to 9600 Baud, if you plug a USB serial port into stretch or
unstable, the stty status shows the default as 9600.

Re: Serial Port Issues

[Chris Rhodin]

I figured it out.  It was user error.  When I diff'd the output of "stty"
from my laptop and server I saw the server had "-crtscts" and laptop had
"crtscts".  It turns out minicom enables hardware flow control by default
and I had changed that default on my laptop somewhere in the past (at least
3 releases of Debain ago).  I thought I had checked this on the server but
either I didn't or I just missed it.  Changing this in minicom made it work.

Are you sure that this is enabled in the BIOS, also some serial ports like
HP have special connectors and layouts.
Best would be to look at the manual first.

I have attached a USB to the server. From there I can log in to the
firewall. I can not use the same port in the opposite direction.

However it is strange that you do get the connection only in one direction.
It could be some kind of special connector

Otherwise I used those to enable the service
