How to add serial port for fedora core 2

jackluli · 06-10-2009, 10:05 PM

I installed fedora core 2 and run command "dmesg | grep ttyS"

Quote:

ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS1 at I/O 0x2f8 (irq = 4) is a 16550A
ttyS2 at I/O 0x3e8 (irq = 11) is a 16550A
ttyS3 at I/O 0x2e8 (irq = 10) is a 16550A

But it show four serial port.
I motherboard has six com port.
3f8/irq4
2f8/irq3
3e8/irq11
2e8/irq10
2e0/irq11
2d8/irq10

How old is your motherboard? FC2 is 5 or so years out of date, so it may well not recognise your hardware. Since Fedora 11 was released a couple of days ago, why don't you try something a bit more modern?

I like the way you didn't bother to answer either question asked.

Board is industrial computer motherboard.
Because customers want to make source code in fedora core 2.

Thank you.

Any solution to this? As I have something similar.

I am intrigued to know how you found out the hex/irq values for files you cannot find! (ie. your dmesg shows the 4 found)

By default only 4 serial ports are configured in the linux kernel. Look for the "setserial" or a similarly named package for your distribution that is used to configure systems with more than 4 serial ports.

Here's a link to another thread about additional serial ports. In one of the posts is yet another link, leading to yet another post. You may find some useful information at these locations.
