Letters to the Editor
m Editorial
The author of the letter published below, not only
criticizes, but also offers its own revision CDOS-modem
(Moscow). Therefore, the wording has found it necessary to
publish a letter to the author variant, without editorial
corrections. The opinions of the author and editors can not
match. - -

For writing this article I have long hesitated to sit down,
but the problem SPECTRUM in Moscow forced me to do it.
Many problems, and I can not relate to all, but I'll try to
say about the basic ...
1.Setevoy Software
Today uses two main programs: CDOS and EMS,
a what if the will is another prog?!
Certainly, EMS provides a wonderful service, but it has
One weak spot - the criticality of the quality of the line, and
work on 600 nice little (IMHO, the most reliable protocol), and
therefore often used by CDOS. It would be nice to introduce EMS
protocol CDOSa (for example, make the button "AUTO"), a well as
the automatic installation optimum speed for the connection.
Very good idea to introduce EMS driver support
Turbo mode for SCORPIONov and KAYev.
In general, a lot of ideas, but who would implement them.
And the improvement of the post, I will not write - a little
figured out.
And finally: CDOS also not forget - most importantly, that
they anyone engaged in close and resulted in a divine form,
then maybe it will be much steeper.
2.MODEMY:
Mainly in Moscow has been and remains CDOS modem on it and
will speech.
For all his dostoinsvah he has too many shortcomings
namely:
1.Kritichnost to the line;
2.Sravnitelno low noise immunity;
3.Kritichnost to the clock frequency of a computer;
4.Raznoboy standard modems in different cities (I personally
heard about the 4-x! CDOS modems);
5.Chastye glitches with the connection: the conflicts with
other long Tami.
I have to CDOS-modem observed the following bug: in state
OFF-LINE halts to "1" transmit - is constantly burning LED
transmit, and line, respectively, becomes occupied. :-(
Thinking, I decided to make the lock port on the M1: a bit
off the 1 st LL1 leg, hung 'sandwich' 555LA3 to 7 and the 14 th
foot, on 1 st leg gave the signal that was on the 1 st leg LL1
(A4) (with fees) 2 nd filed M1 (27 feet processor), 3,4,5-e
feet LA3 combined with the 6 th leg LA3 signaled bitten off at
the 1 st leg LL1; on This revision was completed.
Now, several days of Gluck's not, and before appearing every
2-3 hours :-))).
Wait for additional improvements.
So we must take the whole world, and fully processed
modem scheme, saving it more affordable!
3.Kachestvo communication.
This is our biggest weakness, and I do not even know what to
say on this topic, you can try to move to FM, but it will
require additional costs. But what are the prospects: for
example, automatic routing throughout the CIS!
While all if you have any questions or suggestions
(preferably Cooperation): write to the editorial office NICRONa
- comes required.
