I've just been looking into things like teledisk and anadisk.
These programs still exist on many web pages as sharewere. When
doing a web search, I find that there is a company called NTI that
is selling these as products. They note that they can't sell
these to individuals because someone might use it to copy
protected software. They also state that these programs were
developed under government contracts.
Some how, I don't think these are the same programs that
one can down load. I suspect that they have just stolen
the recognized names. I just wondered if anyone knew anything
about this?

TELEDISK, ANADISK, COPYQM, and all the DOS shareware
formerly produced by Sydex is perfectly okay to down-
load and use.
Chuck Guzis, the original owner of Sydex, produced these
products in the heyday of DOS, and released them as
shareware.
Much later (late '90s), with mainstream interest in DOS
waning, Chuck co-founded NTI as a specialized 'niche'
company (computer security), and sold or transferred
the rights to Sydex's intellectual property (the soft-
ware) to NTI.
At this point, distribution of the Sydex shareware ceased.
NTI was subsequently sold to a large security firm.
But the 'Sydex'-branded DOS shareware lives on at
numerous web sites...and is quite legal and kosher to
download.
I'm not certain if NTI is still accepting registrations,
but they're definitely not supporting these shareware
versions any longer.
If you're REALLY concerned about all this, you could
e-mail NTI and ask them about the current status of the
shareware. You can e-mail directly from their web site:

The current =proprietary= versions of Chuck's original
programs have undoubtedly evolved since the shareware
days, but that doesn't lessen the utility of the older
shareware versions to individual home users.
So feel free to download the Sydex shareware, and may
your mind not be troubled.

Not exactly the chronology. TeleDisk and AnaDisk and CopyQM
were all removed from shareware by Sydex in `93 or `94 - prior
to the release of the Walnut Creek CP/M CD at any rate. The
sale came rather later after TeleDisk had progressed on to
version 2.22 or thereabouts.
The reasons for removing from shareware were several, poor
percentage of registrations and, more to the point, many
requests for technical assistance from unregistered possessors.
The latter were taking up altogether too much of what should
have been productive hours.

22DISK and ANADISK, including myself. I'm surprised by the information in
this discussion. The short version of the facts so far
that all could agree upon seems to be:
The Sydex products 22DISK, ANADISK, and other related diskette analysis products
were developed in the 1980's by Chuck Guzis, who formed that company.
Sydex previously distributed these as trial shareware; and also offered
licensed versions for a fee. Sometime
in 1993-4 Sydex ceased to distribute the trial/shareware versions; but
previous distributions still exist in various CP/M archives. In the late
1990's the rights to these programs were transferred (sold?) to
a company called NTI, who apparently improved upon these programs.
As of 2002 NTI reportedly does not offer these programs "to sale to
individuals" apparently over concerns about bypassing copy protection.
As of 2002 the NTI Web site is apparently http://www.forensics-intl.com.
The details of who owns what and who developed what are interesting but
the bottom line is "Where can I get these products" and "who is
currently selling them". This information should be confirmed and sent
to the comp.os.cpm FAQ. Whether the FAQ will be updated or not is
another matter. I'll at least update my Web site accordingly as above,
pending further corrections or reports by other people in this thread;
and I'd encourage others to update their sites accordingly.
