(Please excuse any duplicate of this message that some of you may
receive.)

Dear MTN Users,

I am removing the MTN files from MC:CPM; and will "shortly" (whatever
*that* means) upload a significantly newer version with MANY new
features and ALOT of bugs fixed.  Release of this new version will be
what I consider premature, but only in the sense that I haven't been
able to install and check out ALL the features that everybody has
asked to be included.  Since some of you have received a pre-release
version of MTN 2.0 in various stages of development, the new release
will be called MTN 2.1 to bring you back in sync.

I must add that the reason for doing this was prompted by a rather
embarrassing discovery of a piece of code that has been in the program
from its beginnings which was lifted from another modem program and
seemed to work.  In tracking down a bug near that code, I found that
what I had assumed to be correct was not.  THIS ONLY APPLIES TO USERS
OF MTN 2.0 AND BELOW WHO HAVE A D.C. HAYES MODEM.  THE PMMI CODE IS
CORRECT, EXCEPT THAT IT DOES NOT HANG UP THE PHONE WITH THE TERMINATE
COMMAND.

So, rather than leave this faulty code around for even more
unsuspecting people to pick up and not let me know they have it (so as
to be on the mailing list for upgrade announcements), I am removing it
from further circulation.

My sincere apologies for any inconvenience this may have caused you.

[For those of you interested in what the bug was that got me upset:

For some reason, the original author of this section of code decided
to turn on the transmit enable signal BEFORE dialing the number,
rather than AFTER receiving the carrier detect signal from the remote
modem.  What lead me to check this out was that I was trying to speed
up the dialing back to specs and could not find out why another
auto-dialing modem program I had was successful in completing calls,
while my version, using the same timing was not.  I also discovered,
in the same section of code, that the modem setup was not correct
either.  Thus the withdrawal announcement.
