Serial Ports
Hallo,
ich habe Debian Etch gerade neu installiert.
Wenn ich die 4-Port-RS232-Karte bei der Installation weg lasse, dann
findet sich die GPS-Karte (Oxford-Chipset) unter /dev/ttyS1
Wenn ich die Karte wieder einbaue, dann findet er die GPS-Karte nicht.
Also habe ich die Reihenfolge der Karten vertauscht. Jetzt findet er die
GPS-Karte immer. Und der GPS-Part funktioniert reibungslos.
Allerdings möchte ich die RS232-Karte (4-Ports) auch aktivieren.
Folgende Angaben von mir zur Sache:
lspci (OHNE eingebauter RS232-Karte)
02:0e.0 Serial controller: Oxford Semiconductor Ltd OX16PCI954 (Quad
16950 UART) function 0 (Uart)
02:0e.1 Parallel controller: Oxford Semiconductor Ltd OX16PCI954 (Quad
16950 UART) function 1 (parallel port)
lspci (mit eingebauter RS232-Karte)
02:0e.0 Serial controller: Oxford Semiconductor Ltd OX16PCI954 (Quad
16950 UART) function 0 (Uart)
02:0e.1 Parallel controller: Oxford Semiconductor Ltd OX16PCI954 (Quad
16950 UART) function 1 (parallel port)
02:0f.0 Serial controller: Oxford Semiconductor Ltd OX16PCI954 (Quad
16950 UART) function 0 (Uart)
02:0f.1 Parallel controller: Oxford Semiconductor Ltd OX16PCI954 (Quad
16950 UART) function 1 (parallel port)
Das zeigt mir, dass zumindest 02:0e die GPS-Karte ist.
Der folgende Befehl zeigt interessanterweise (bei NICHT eingebauter
RS232-Karte) folgendes:
borec:~# clear; dmesg | grep -i ttys
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
00:11: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A

ttyS2: detected caps 00000700 should be 00000100

ttyS3: detected caps 00000700 should be 00000100
0000:02:0e.0: ttyS3 at I/O 0x4830 (irq = 7) is a 16C950/954
Wo kommen /dev/ttyS2 und /dev/ttyS3 her?
Unter /var/log/messages findet sich noch folgendes (mit eingebauter
RS232-Karte):

Grub habe ich dann "pci=assign-busses" angehängt und damit gebootet.

Benötigt Ihr noch mehr Infos?
Wie komme ich weiter?
Warum werden nur 4 Ports aufgelistet, und unter lspci sogar nur zwei (2
seriell, 2 parallel)?
Viele Grüße und vielen Dank
Michael
