Hallo,
für eine kleine Testlandschaft mit Geräten, die nur serielle Schnittstellen haben, benötige ich auf dem PC ebenso sechs serielle Schnittstellen. Der PC hat zwei Schnittstellen onboard, dazu habe ich noch zwei PCI-Karten mit jeweils zwei seriellen Schnittstellen (1x MosChip, 1x Sunix Sun 1989). Leider bietet das System allerdings trotzdem nur ttyS0 bis ttyS3 an, wenn beide Karten eingebaut sind. Beide Karten funktionieren, wenn jeweils nur eine davon eingebaut ist, d.h. auch dann gibt es jeweils ttyS0 bis ttyS3 und alle Schnittstellen wurden auch jeweils durchgetestet. Klar, das Problem ließe sich durch einen USB-zu-2xseriell lösen (funktioniert), aber ich würde ja schon gern wissen, warum es mit den Karten nicht klappt bzw. was zu tun ist.
Vorweg noch, der PC ist eine alte Möhre (P4) und es läuft noch das bis zum Ende durchgepatchte Mageia 5 darauf. Der Rechner hat aber keinerlei Verbindung zu irgendeinem Netzwerk, insofern finde ich die Weiterverwendung vor der Verschrottung akzeptabel.

Hier die Ausgabe von lspci und dmesg jeweil mit nur den
- onboard Schnittstellen,
- onboard & MosChip,
- onboard & Sunix,
- onboard & MosChip & Sunix :

Hat wer eine Idee woran es liegt?

Es scheint, als ob die Sunix-Karte nicht erkannt wird, wenn die Mosix-Karte im System ist.

Vor 20 Jahren (oder länger, als ich noch etwas mit seriellen Schnittstellen am Hut hatte) musste man jeder Seriellen einen eigenen IRQ zuweisen. Das mag heute anders sein.
Jedenfalls fällt auf, dass beide Karten die IRW 3 und 4 nutzen. (Die eine zusätzlich 17, die andere 22).

Sucht der Kernel (bzw. das Init-System) überhaupt mach mehr als 4 Seriellen?

Fragen zu mehr als 4 Seriellen im Internet sind naturgemäß sehr alt und dort endet es meist mit manueller Konfiguration. Aber seitdem hat sich die Methode, wie Hardware eingebunden wird, stark geändert.

Gibt es noch Handbücher zu den Karten, wo evtl. etwas über die Parallelnutzung mehrere Karten gesagt wird?

Hallo!
Kenne ein ähnliches Problem aus den Neunzigern, als Vernetzung so richtig in Schwung kam.
Die NoName Netzwerkkarten für 10 Mark konnten nicht zu mehreren in den Server gesetzt werden, es war immer nur eine ansprechbar. Die 3COM-Karten waren beliebig zu reihen.
Gruß

Ich habe schon befürchtet, dass der Kernel einfach auf gar nicht mehr als vier serielle Schnittstellen eingerichtet ist. Ich könnte mal schauen, ob ich das durch Ausschalten der Onboard-Schnittstellen verifizieren kann.

Naja, der Kernel kann mehr, aber ggf. steht der Standard vom jeweiligen Treiber noch auf 4.
Siehe z.B. https://stackoverflow.com/questions/262 ... s-in-linux

Code: Alles auswählen: [doktor5000@Mageia7VM ~]$ zgrep -i CONFIG_SERIAL_8250_NR_UARTS /proc/config.gz CONFIG_SERIAL_8250_NR_UARTS=4
