I'm trying to get this behaviour too, but I think the problem is that you
need to have the approprite MIB loaded which tells Scotty that the
octet-string is to be interpreted as ASCII (rather than any other object
which could be represented as an octet-string: after all the string could
represent non-printable characters, and whilst Scotty could take a
heuristic approach to deciding what to do with them, I guess Juergen has
taken the approach of doing the correct rather than the clever-clever
thing).

I find that traps from our Bay Accelar (nee Rapid City) switch get
interpreted and displayed as text, whilst traps from HP switches are shown
as octet strings: I have the rapid city MIB (there is only one) loaded,
whereas of HP's directory full of assorted MIBs (on the CD supplied with
their switches) I haven't (yet) found the right one(s) to load (and
haven't gone for the brute-force approach of loading them all!).
