Mike, is it?

There never is any fading, noise, scratchiness, or interference heard

It is always possible that the local phone company has degraded the 
service recently.  Transfer speeds *are* down somewhat from August 
when connected to several local BBS's at which there has been no re-
dial or CRC problem.  I checked to see if connecting in the house via 
another (internal) extension might help.  What I haven't tried is un-
plugging the several instruments that are scattered around the house 
on that same line to see if one has gone bad unbeknownst & is causing 
these faults..
 HS> If you want something very basic to initialize the modem, you

I will certainly give that a try.  Meanwhile, due to having to call 
long distance and finding Fido is as fast or faster, I left a note 
last night on the Hayes Support BBS that I prefer to use this route 
over calling there, especially if it's essentially the same folks in 
each case who will answer..
(Well, maybe that was a mistake, after all.  I never saw any reply 
get to this area.)
Although I still wonder where the very first query that I uploaded 
to your support BBS disappeared to..
Maybe a second line would be worthwhile.. Craig Ford suggested adding 
a "Q6%C0" for calling those BBS's I have trouble with.  I have the 
slightly more detailed manual from the Accura 14.4, didn't find that 
one in there, but there was an S Register setting for bad lines in 
there somewhere.
(In that particular regard, I cannot determine from Qmodem's manual 
how/where that code of Craig's is tucked into the terminal software, 
or where/how it would store something for the S Registers.)
