Ok folks, I'm going to start pursuing the new flashrom soon.
Currently my modem reports (with date translation):

Supervisor Date - 1995-01-25
DSP Date        - 1994-12-02

I am expecting to get a file called SDLV34P.ZIP which has:

Supervisor Date - 1995-07-18
DSP Date        - 1995-07-05

Hopefully I will obtain and install this stuff tonight.

BTW Paul, can you send me the old files so that I can go back
to them if required?

David Drummond, can you confirm that the dates reported by ATI7
are as above on your modem?

BTW, the manual for the USR Courier I am using says that it is
"V34-ready", and "V34" is not actually mentioned as one of the
supported standards.

BFN.  Paul.
