Multi-I/O-Karte

Hallo,

in einem FreeBSD 4.3 Rechner steckt eine PCI-Multi-I/O Karte
mit 4 COM-Ports (Gibts auch mit 8), die ich nicht zum laufen
bekomme.

Für ISA-Karten gibts ne Kernel-Option, bei diesem Ding aber
wird das wahrscheinlich nichts bringen.

Wie bindet man die am besten ein?

Für Linux gibts eine Anleitungm die ich aber nicht auf BSD
umzusetzen wüsste:

[Auszüge]

(1) Find the available serial ports
#setserial /dev/ttyS0 -a (COM1)
#setserial /dev/ttyS1 -a (COM2)
#setserial /dev/ttyS2 -a (COM3)
#setserial /dev/ttyS3 -a (COM4)

(2) Find the PCI card resource ( IO port address & IRQ) for
      the serial ports
Please enter the command "#more /proc/pci".
The response is similar to the following
      
       …………………………………………………………………..
       …………………………………………………………………..
       Bus 0, Device 11, function 0:
                   ^^
Serial controller : Unknown vendor Unknown device (rev 1).
Vendor id=1409, Device id=7168
Medium devsel. Fast back-to-back capable. IRQ 10
                                              ^^
I/O at 0xef80 [0xef81]
        ^^^^ ^^^^

>From the /proc/pci file, it is possible to find the PCI card's IO
port address and IRQ. Especially, the SUNIX card always shows

"Vendor id=1409, Device id=7168".

(3) Configure the parameters for ttyS2 & ttyS3

for SUNIX 4025A card (PCI 1S), please enter (if ttyS2 is free)
           # setserial /dev/ttyS2 port 0xef80 UART 16550A
                       irq 10 Baud_base 921600

for SUNIX 4036A card (PCI 2S), please enter (if ttyS2 & ttyS3 are free)

           # setserial /dev/ttyS2 port 0xef80 UART 16550A
                       irq 10 Baud_base 921600
           # setserial /dev/ttyS3 port 0xef88 UART 16550A
                       irq 10 Baud_base 921600

(4) Check the setting for ttyS2 & ttyS3

      Please enter # setserial /dev/ttyS2 -a
      The response look likes below

      /dev/ttyS2, Line 2, UART: 16550A, Port: 0xef80, irq: 10
                 Baud_base: 921600, clos_delay: 50, divisor: 0
                 closing_wait: 3000, closing_wait2: infinite
                 Flags: spd_normal skip_test

(5) Then the ttyS2 & ttyS3 are ready for application
      (eg. minicom -s or xminicom -s or Kppp ...)

Auf Wunsch kann ich das gesamte Dokument per pm schicken.

Gruß,

Martin
