Hyperterminal / Putty Question

Hey guys so I have a few dpc2100 modems that have messed up jtag ports but boot just fine. I use to use hyperterminal for programming these. Years ago there was a very good tutorial over on SBH but it seems that its been lost as I cannot find it and its been so long I dont remember all the setup steps anymore.

Does anyone have a copy of this tutorial or if you could help me get my putty configured correctly would be great.

Thanks guys
