Pie a la Modem
July 1993
Copyright 1993 Daniel J. Barrett
Many true Amiga fanatics have modems connected to their computers,
or even directly to their brains. But how many of us truly understand how
these miraculous yet mysterious devices work? Do YOU understand? I sure
don't! But that won't stop me from explaining it anyway, and in great
detail. This article will tell you more than any sane person would ever
want to know about telecommunications, modem protocols, and how to waste
your life in front of the screen.
Our first big question is: where did modems come from anyway?
Well, a bunch of years ago, a generic famous person answered his telephone
and discovered, to his surprise, that it was emitting strange, high-pitched
noises. Believing that this was an attempt by space aliens to contact
humans, he built a device that could turn the weird noises into text.
Sadly, this resulted in failure, mainly because the noises were actually
being produced by some squirrels chewing on the phone lines. But the
inventor decided to sell his failed device anyway; and through brilliant
marketing, modems are now in common use for non-extraterrestrial purposes.
Interestingly enough, there is some new, controversial evidence
that modems were actually used back in Paleolithic times! Archaeologists
have discovered what appears to be a primitive FAXmodem carved out of stone.
It communicates at a paltry 0.0003 baud and has no flashy lights on the front
panel, but it appears to have been sufficient to transmit important business
memos such as, "Meeting tomorrow, sunrise. Bring mastodon."
The word "modem," according to a bunch of random computer geeks I
asked, is supposedly an abbreviation for "MOdulator/DEModulator." But
truthfully, it's an acronym for "Mounds Of Data Emitted Melodiously," in
honor of the screeching sounds your roommate hears when he unwittingly
picks up the hall phone, disconnecting your four-hour-long download.
So what are those screechy noises anyway? Well, they are an
audible "encoding" of your data, transmitted to another modem using a
communications protocol, which is a techno-geek term meaning "screechy
noises." There are many such protocols, all with fun, cryptic names like
"MNP-5," "V.42," "OB-GYN," etc. What do these mean? Essentially,
they are ratings of how many flashy lights are on the modem's front panel.
The more "protocols" your modem supports, the more lights it has. An
extreme example of this fad is seen in the popular SuperFAXModem V.32bis,
which has a whopping 64 lights (yes, the lights continually make "whopping"
sounds) that continually change and spell out insulting messages on the
display.
Once you have settled on the features you want and purchased a
modem, the only other component you need is a telecommunications program.
(Well, you might also want someplace to connect to, but this is a trivial
detail. The important thing is to have the modem and software so you can
brag to all your hacker friends about what a "Cool Dood" you are because
you can spell "BBS".)
Anyway, let's suppose you have your telecomm program and modem all
set up and running. You click on a a "dial" gadget or some such nonsense,
the modem dials the phone number, you hear the famous screechy noises, and
finally a message like:
CONNECT 2400
appears on your screen. This means that your modem has successfully
connected to another modem at a rate of approximately 24 dollars per
second. The number will be higher (9600, etc.) depending on how much
your modem cost. Advertisers will tell you that this number is a speed
measurement, but don't believe them! In fact, all modems operate
at the same speed, but the manufacturers of course want you to buy the
modems with the higher connection charges.
Once you are connected, you are ready to access vast databases of
information, make plane reservations, communicate with people around the
globe, and be incredibly productive. Ha! Who are you kidding? You'll
probably spend all your time playing "Bunny Blaster Wars" on the local BBS.
By the way, if you are in need of telecommunications software,
you might want to check out BLAZETERM, made by the same company who brought
you BLAZEMONGER (see the April 1993 WeirdBench, if you dare). BLAZETERM is
the ULTIMATE telecomm program, especially for ease of use. Its built-in
phone database already has every BBS number in the world stored, so you
don't need to type them in yourself. In fact, you don't need to type
ANYTHING at all, because BLAZETERM already KNOWS what you want to find out
and does the typing FOR you! Heck, you don't even need a modem! Or even
an Amiga!! Just toss BLAZETERM into your desk drawer and leave it alone
while it does all your work! Better yet, you simply can send BLAZEMONGER
INCORPORATED a bunch of money, and you can forget about the program
altogether. What could be easier?
I hope you've enjoyed our little tour! Until next time, remember
these famous words spoken by the inventor of the modem: "Eeeeeeeeeeeeee
KKSSSSSSHHHH!" I think there is wisdom in there for all of us.
