Re: AS400 telnet traffic

If I remember correctly - the AS400 may be encoding EBCDIC and that's why it 
looks like gobbedly-gook.. I could be wrong, but I think that's it...

I have captured some AS400 telnet traffic with tcpdump on port tcp 23.

It seems to be encoded in some way, because I only can see a few 
initial cleartext words, like: IBMRSEED, KBDTYPE, CODEPAGE, IBM-
3477. The following stream of words are unreadable with encoding or chiper.

When I see the dump with Ethereal, the decoded data are like:

\000\r\022\240\000\000\004 and goes on...

Does anyone known how to decode this capture to get the cleartext form?

Thanks in advance,
