I'm trying the 860hdlc driver for linux 2.4. Could you help me?

Hello, I'm newbie.

I'm writing  the HDLC driver for mpc860.
And, I try to find the best to do. The time frame is very short.

Before preceeding,  I surfed the goole group, and found the web link
contained, but link is broken.
If anyone have the driver, could you share it with me?

Thank you.
