Hi all,

i've running DSL 1.5 on a 3,5-inch-SBC with a PC104-Expansion, on which is sitting a 8xRS232-Card. So i have at least 10 serial ports, but i can use only 8. It seems that no more ports are provided by the kernel, so i have to compile it by myself.

Now i didnt find any knoppix-kernel from Knoppix 3.4 around the net, can you give me some working link? Or can someone tell me how to apply the kernelsources.dsl as a patch to the Standard-Kernel 2.4.26? Or any other solution to get all serial ports to work?

Thanks in Advance, Jens

Maybe you can use more ports but the device names have not been created yet?

In that case, choose Upgrade to GNU Utilities from the menu and then use the "mknod" program to create more serial port devices like these instructions:

You can get the kernel sources inside the KNOPPIX_V3.4-2004-05-17-EN.iso livecd

Thanks, your message pointed me in the right direction. I've created the devices before, but i've forgotten to chown them to root:dialout (they were root:root). Now all ports are visible in /proc/tty/driver/serial as they should do.

Thanks, Jens
