     Here, a few days ago, I read an article in
Faultless'e about the new modem for SPECCY
(ZSC MODEM). I just could not keep silent,
as they are, the authors of this paper,
promote your modem, obsiraya
others. In this case, it is done in the spirit
all-modems - not modems, and our
Modem - a modem. "And, specifically
about the new modem did nebylo said.

Quote line article:


     "What is a BBS and what opportunities
provided to users was
sufficiently detailed in
electronic newspaper and magazine ZX News
ZX Format, so I'm on it
not dwell and get down to business
(Long overdue!). Now specifically about our
modem. "

Noticed this he (the author) a second time
specifically going to tell us about
his miracle modem.


     "No doubt many of you
known to some already existing and
actively used, modems SPECCY.
What is the difference between this modem from
others.

     The word modem is short for
words modulator, and as
appeared in most of the actively
promoted to date
"Modem" for SPECCY (ZX MODEM, VICCOM,
C-DOS) have neither the one nor the other, that is
in essence they are not worthy of the name
"Modem" and the most correct such
"Fun" called "the matching". "


     How can call if ZSC Modem,
which is compatible with VICCOM.


     "Some offer to connect to
SPECCY internal modem for PC
compatible machines (HAYES). With regard to
popular modems (14400) - they
will cost you $ 75 (minimum), and
notorious modems for 2400 are no longer
available, they can get to work and
only used (a good chance to some
PC user to finally get rid of this
devaysa obsolete as of
used toilet paper). "

Here's the interesting thing obtained if
cupula people used the device (the same
Spectrum), then he got okazyvetsya
a piece of used toilet paper.
I am interested authors comp (Spectrum)
bought myself a zero?


     "Moreover, as shown by experimentation,
In most cases, even with regard to
one ATS, they operate at an average
rate of 900-1200 bit / s, because they
clearly not meant for "shovels"
the lines. "

Well Sorry me, I have a modem is on
2400 and it almost always works
at maximum speed.


     "If you want to take it to communicate
with PC BBS, I can assure you that
sisopov lot of this "brake" just
will not start (requires at least 9600). "

Nonsense! There are still good people and BBS,
who work in 2400. Yes, and if
people pick up yourself Hayes modem'y, then
BBS appear specially for the
Spektrumistov.


     "Not to mention that on the PC in 1980
characters per line, and you??

Well this is no longer a problem, a pair
three circuits, and you have the same 80
characters per line.


     "You should also pay attention to
galvanic isolation of the six signals
optocouplers, which allows the modem
fully monitor the line and determine the number. "

Determine the number? It rulez.


     "There are options for connection
modem directly to the wires at the same time,
Naturally, the speed will
maximum. Thus, we can
connect more than two computers and
create a network, and since the modem will not
restricted to a narrow band of frequencies
telephone service - it can be rebuilt
at a high speed - up to 19200
BPS. It may also be connected to
radio (this is the most significant
for those who do not have a phone, but there
each computer, living a relatively
close). "

Well, just no words!


     "In my opinion, the ZSC modem us
managed to achieve the greatest advantages
at the lowest price. "

Here I would like to know the price, well at least
in comparison.


     "The modem connects to muzprotsessoru
with two I / O ports - AY-8910
YM2149F. You can connect the modem to
tire processor. "


     "Now specifically about the opportunities
modem related software
Enablement. "

When we finally hear from the authors
specific advantages and opportunities
modem.


     "This modem allows you to create
based on it completely
automated BBS. You can
use the convenient and popular in
Russian program MACRO MODEM (MMD),
which, by the driver ZSC-MODEM'a,
will work, using all
opportunities MMD v2.20 (read ZX FORMAT
# 6) and a modem, as in our protocols,
and on protocols VICCOM, which will
enable you to communicate with BBS to
these modems. Especially because in many
ATS is the opportunity for free
long-distance call (read ZX-News
20-30)! In this case, you, in addition to the full
Compatibility VICCOM get
additional features - the removal of
tube, the reaction to the challenge (possibly
only VICCOM'e, "with bells and whistles"). "

And Hayes'e without bells and whistles!


     "Caller ID, more
high-speed and reliable communication protocols
Data compression and various
methods of error correction. Yet made
ten minutes with an average speed
from 600 to 9600 baud. "

Originlno! At Hayes'e average speed
from 1200 to 57600 baud. Cool yeah!


     "So, think for yourself, a modem
you better choose for Spectrum. "

Both hands.

I did something to have against ZSC-Modem'a,
because every invention is entitled to
life. However, promoting your modem, do not
necessary, Sorry for the indiscreet expression
smear other modems, because of the user,
going to buy myself modem,
there will be no desire to do it. Since it is impossible!
