According to the Hayes standards, "if the modem is off-hook,
it will neither initially wait nor attempt to detect dial tone
before proceeding." (*) So, take it off-hook with ATH1, then
dial using ATDT..... as described above.

Yada, yada, yada - I'm not referencing how much "natural resources"
more than one tv will use (although the pwer company will charge
you for the difference...). It seems the cable company is incapable
of designing a method of reliably metering how much "information"
you're using. So they bill you their worst-case estimate.

No, this is exactly the point. The power company has gone to the effort
of using a meter that only bills you for the resources you use, if you
use a bunch of flourescent lights, or if you try and heat the house
with the stove, they'll bill you for what you used. Seems simple
enough to me. It seems like the cable industry is trying to say "you've
got 20 power outlets in your house, we know, 'cos we've tested it.
Therefore you owe us $x". And people fall for it - go figure.

BTW - I don't have cable :-)

	It is common to use oscillator, counter and a BCD-1/10-decoder.

see S1S9 records which are this long.

Perhaps something to try is converting these `long' records to short
ones.  E.g. this record:
  S123D0008600BDC285FEC001140301BDC156432607BDC110BDC0BA3B432607BDC237BDC0C4

would become these two:
  S113D0008600BDC285FEC001140301BDC1564326??
  S113D01007BDC110BDC0BA3B432607BDC237BDC0??

(I was too lazy to calculate the proper checksums, so I just put in
`??' instead.)  Notice that `S123' (16-bit address, 35 bytes to follow)
changes to `S113' (16-bit address, 19 bytes to follow).

 Ever looked inside one of the original converters?
 I have one, it has 7 1N4001 diodes i series... (the CD wants 5-7 V in)
 Most batteryoperated devices aren't that touchy about input voltage,
 there is a small ;-} difference in battery voltage between fresh batteries
 at standby and almost dead at full output...

Date: 6 Nov 92 19:48:12 GMT
Organization: Edinboro University of Pennsylvania

I have recently had to attempt repairs on a camcorder but the problems
were to numerous to correct with anything short of a main circuit
board replacement.  m The micro-proc controller is not reponding
appropiatly (things are happening but they are not right), and the
video modulator/demod (its all on one chip) near the u/p is also
fried.  

This unit has just returned from a trip to Europe where it went
through several airports (and I presume) the x-ray scanners.

What I am wondering is what is the probability that the x-ray
unit(s) may have fried the chips or is it more likely that travelling
in some aircraft hold (possibly unheated and/or unpressurized)
caused these problems.  Or is it more likely that the various jolts and
bumps may have caused at least two (and quite possibly more) seperate
failures at the same time?

Care to venture an opinion?

   Everything is fine *except* that I don't get any thing on channels above

							   Andrew MacRae

Although the channels on your television are numbered in smooth 
increments the frequencies that they select are not.  The television 
channel allocations are in at least three (four?) bands of frequencies 
with other services occupying the space between them.  There is a large
gap between channel 6 and 7 and another, larger, gap between 13 and 14.  

Channels 14 and up are in the Ultra High Frequency (UHF) band.  Those
frequencies do not lend themselves to wide distribution via cable.
Your cable provider cannot and therefore does not send programming 
via UHF frequencies.

"But" you say "my cable converter box tunes channel 14 just fine."

Aha! Here's the confusion...  Broadcast channel 14 is NOT the same
as cable channel 14.  They are at different frequencies.  The 
broadcast channel 14 is a UHF frequency but cable channel 14 is
a VHF frequency.  

Actually, since the cable system is a closed system, your cable provider
is free to use any frequencies they want to use.  Even frequencies
that are allocated to other services.  I can't find my list of 
cable television frequencies, but I wouldn't be surprised to find
that cable channel 14 and the next half dozen or so were cable-cast 
on the frequencies that lie between television channels 6 and 7.

He needs a visit to the pediatrician for an examination and a least a
CBC (complete blood count) and a test for infectious mononucleosis
if this doesn't clear up soon.  It doesn't sound like "growing pains".

Your mother and pediatrician could have taught you any of many simple
behavioral methods to combat your tendency to vomit.  People can often
avoid vomiting in many situations by taking a few deep breaths, etc.
Most adults don't want to be treated like kids, tricked or manipulated,
and suspect they're being tricked or fooled or exploited by MDs even
when they're not.

Lying to patients (even with effective placebo trickery) undermines the
trust and mutual respect which ought to characterize the doctor-patient
relationship.

Those commercials are sponsored by Glaxo Pharmaceuticals to promote a very
expensive drug of theirs called Zantac which suppresses production of acid
in the stomach.  I'm on Zantac right now and it costs about $1 per pill.

Basically, anyone who has heartburn every day (not just after eating certain
things) probably has something wrong with the gastroesophageal sphincter
(the valve at the top of the stomach that keeps acid out of the esophagus).
"Something wrong" could be an ulcer, a hiatal hernia (part of stomach
sticking through the diaphragm), or simply an irritated area that needs to
heal, but won't heal until you give it several weeks without acid.

The things that helped me most was a very low fat diet (because fat tends
to open up the sphincter).  And of course Zantac.

Why do you think that?  Do you think those who claimed to tell the
future from the entrails of animals "stumbled onto an actual effect"?
There used to be many, many schools of homeopathic medicine in the
US.  Now there is only one (Hahnemann) which wishes it could just
be shed of homeopathy anyhow.  Why do you suppose this is?  Conspiracy?
Could it be that homeopathy is just another timeworn superstition
that has outlived its era?
