socat ser2net

[Oekel]

(Ich hoffe ich bin in der richtigen/bestMatch Forenkategorie)

Ich verzweifel so langsam an einer offensichtlich wirklich einfachen Aufgabe:

Etliche RaspberryPies (1,2,3B,4) bzw. ein beliebiges Linux als USB/Seriel Server + ser2net
Einige Docker-Images bzw. beliebige Linux Clients mit tcp native support oder socat
Vorweg: Ganz falsch kann meine Konfiguration nicht sein, denn 1/3 Geräten funktioniert!
Server:

# Find detailed documentation in ser2net.yaml(5)
# A fully featured configuration file is in
# /usr/share/doc/ser2net/examples/ser2net.yaml.gz
#
# If you find your configuration more useful than this very simple
# one, please submit it as a bugreport

Den aeotecstick7 kann ich mittels tcp://192.168.1.14:4000 (aus einem Docker-container "Z-Wave JS UI") erreichen und liefert auch korrekte Daten.
Der razberry7 hängt am echten seriellen Port und funktioniert NICHT tcp://192.168.1.14:4001 (aus einem Docker-container "Z-Wave JS UI")
Den 2. USB ender3pro versuche ich über:

socat -d -d pty,link=/dev/ender3pro,raw,echo=0,perm=0777 tcp:192.168.1.14:5000

ins Programm (OctoPrint unterstütz kein tcp-device) zu bringen. Doch auch hier scheinen keine vernünftigen Daten anzukommen, obwohl:
Über Telnet eine Verbindung möglich zu sein scheint:

root@ubuntudocker:/dev# telnet 192.168.1.14 5000
Trying 192.168.1.14...
Connected to 192.168.1.14.
Escape character is '^]'.

Nun frage ich mich wie man hier analytisch und systematisch Stück für Stück zum Ziel kommen kann?
Welche (erweiterten) Optionen/Parameter bietet mir ser2net, welche socat?

Gibt es bekannte Einschränkungen mit welchen Geräten es NICHT (niemals) funktionieren wird, oder sollte es persee mit allen Seriellen devices klappen?

Würde mich riesig über jede erdenkliche Hilfe freuen (insbesonders weil ser2net in so vielen Foren angeschnitten wird und nie allumfänglich auf Pitfalls und dergleichen eingegangen wird)

Hi,

auch wenn ich mit Deinem Vorhaben nichts an der Mütze habe...

Welche (erweiterten) Optionen/Parameter bietet mir ser2net, welche socat?

"man"-pages lesen? Direkt auf dem System via man ser2net bzw. man socat oder direkt im Browsser:

- https://linux.die.net/man/8/ser2net
- https://linux.die.net/man/1/socat

Nun frage ich mich wie man hier analytisch und systematisch Stück für Stück zum Ziel kommen kann?

Ich würde in erster Linie mal das Logging hochschrauben und die Logs durchforsten (s. z.B. man socat - "CW-d -d -d -d", damit dürfte einiges zu sehen sein).

Leider nichts, was mich schlauer macht:

Also er loopt fröhlich die PIDs durch, was ja auch nicht richtig sein kann....

Nur der Vollständigkeithalber.
Ich habe es nun ohne socat hinbekommen (reines ser2net + direktes abgreifen des streams in den Endprogrammen)

Der Fehler lag in Zeilenumbrüchen meiner ser2net.yaml
Schrecklicherweise stand dieses Fehlverhalten nirgends in den Logs bzw. meine IDE hält Zeilenumbrüche für gültig in yaml

Hier nun nur noch schnell die funktionierende Konfiguration:

define: &banner \r\nser2net port \p device \d [\B] (Debian GNU/Linux)\r\n\r\n

  accepter: tcp,4000

Wenn sich die Programme verbunden haben, sollte es dann so aussehen:
