Fortunately, Fedora Core 2 supports PCCOM PCI 4/8-Port cards.

 

Like other PCI-type multi-port cards, the device names for the RS-232 ports in the installed PCCOM PCI 4/8-Port card are assigned depending on which ISA cards installed. You may reference the attached file, serial.h (include/asm/ in the kernel source) to look up which ISA cards are assigned by default. For example, the standard COM1(0x3f8), COM2(0x2f8), COM3(0x3e8), and COM4(0x2e8) always occupied /dev/ttyS0, /dev/ttyS1, /dev/ttyS2 and /dev/ttyS3, if no other 8250-based multiple-serial-port cards installed, the first device name for the first port of the installed PCI 4/8-Port card will be /dev/ttyS4.

 

How you can assure that Fedora Core 2 kernel does recognized the installed DCI PCCOM PCI 4/8-Port cards?

1.     Using the command, cat /proc/pci, to lookup if “PCI Device 6666:0001” or “PCI Device 6666:0002” are listed or not and their assigned I/O address and IRQ

2.     Using the command, “setserial –a /dev/ttyS4” (if installed PCI 4/8-port cards whose names are ttyS4 – ttyS7) to check if the UART, Port address and IRQ are consistent with the setting displayed while cat /proc/pci.

 

If you can make sure the Fedora Core 2 kernel does recognized the installed DCI PCCOM 4/8-Port card, you can use the RS-232 ports like other RS-232 ports.
