ZXNet

Nets - On the Minsk ZX-Net.

                 Nets

   So, a few words about the work
MG ZX-Net. All write a below - in person
my opinion ...

   1) The work of BBS.

   I want to say for those wishing to
open up their BBS (and already is open):

   Firstly, if you open a BBS, then
it should work, not the number of
list (well, I do of course, unless there is
technical reasons ...).

   secondly, the BBS should be something
interesting (and whenever possible)
otherwise it will be enough to download your catalog once a 
month 

   Third is important to the server
had a good relationship with different areas of the city

   Fourth, if the server (or sysop)
suddenly broken off to work let him report on the
in advance

   2) At the expense of C-DOS.

   It's certainly a big glitch, but not fatal ie it can be 
cured. While it may be once in SIDS. In general, I did not I 
know that it is better to kill the bugs in the existing 
program, or just make a new one (with all the twists). First, 
faster. The second I can not do alone.


   3) As for the comments that
poorly configured modems, etc, etc. I
report that all modems are configured for
mode TURBO2, where the rate is 1,5 times more than in the 
TURBO. On the line 49-49 everything works fine, other Lines 
sometimes does not work and TURBO ... 

   4) Is it possible to increase the speed?

   There are several obstacles to the transfer
at high speeds:

   a) speed MT Z80

   b) bandpass filters that are installed on
All ATS cut the treble. Common frequency modulation is not going
(Since there is a threshold frequency for
computer and telephone for Linney).
Ie increase in the rate (at least
more than 1,5 times) for the scheme
Physically impossible. Even IBM modems
at 4800 and beyond use completely druie principles: the phase 
and double phase modulation. What this means in two

words: to create and configure a similar scheme
In amateur conditions is practically impossible.

   5) Speaking of IBM modems.

   I did not understand those who believe
Here's what Hayes steeper all. First have
clarify - what kind of Hayes. If Hayes
2400, he abruptly only at the price and built-in processor for 
data packing (not have nothing zipovat).


   Whether the currently Hayes? I like to
market, but nothing suitable has not found. By
a newspaper ad, though seen
Hayes-2400 for $ 20. Software Support and
connection scheme is now absent. But
say, even if I have been: say,
How many people would be designed in such a network
Hayes'ah? You can in fact deliver and 14,400 for
$ 60. In my price also plays an important
role: the higher the price of the modem, the less
network. This I think is understandable.

   6) In general, my opinion is that the work
ZX-Net is not enough Consignment
(At a price of 60 rubles per minute), I wonder who
how much to pay (or rather - preplatil) for
phone in the last month? Here I am, for example,
overpaid 80 pieces (although connects each day).

   7) Network ZX-Net currently exists in Moscow, St. 
Petersburg, Minsk, and possibly somewhere else (tell me where). 
Well, let's say call to Russia is very expensive (7t/min).

But what in Belarus is not enough to make a call? In the near 
future network ZX-Net poyavyatsya (or have already appeared) in 
the following cities: Brest, Grodno, Bobruisk, Mozyr .... 
Relationship with Brest, for example, at night (22.00-08.00) 
costs 850rub/min (if certainly has not risen in price), but 
it's not this: within the country to liaise

between the cities in my opinion is very real.
The only question is how? The most simple
option - C-DOS'om. Well, I do not know, in principle,
it is possible, but to me something not so wish. Must find 
other ways: 

   1) the relationship through other networks (FidoNet, 
InterNet, DenegNet ...) Of course, once or twice You can 
negotiate with anyone, but always fail if you do not find an 
interested person. So far I can only offer from him to accept 
mail for Moskow ZX-Net and the Echo (Brest). Communications

via email. About sending prog it does not go yet.

   2) Actually, if you think well, then
special problems should not be: it just takes a communication 
center for the city. The main thing - to make it work 
permanently. How to make this site, here it is necessary to 
think together. If we succeed in this terms of an agreement, it 
will be possible to make inter-city network on a "points" that 
connect the local (urban) networks. Incidentally, such a 
structure exists in Fido. 

   3) it is obvious that the Point should be equipped with 
enough high-speed modem and maybe ... computer. Perhaps even

IBM. Or connect to the fastest Hayes
Spectrum (in principle this is possible, however, as I 
understand Hayes will not work in real-time with the Z80: ie 
first, for example, a program of perekachivatesya RUShek in 
Memory Hayes'a, then programs the Z80 Hayes to transfer and 
continue with more Quick cent-a Pr. transmission). Well,

I digress ...

   In principle, everything can be done differently, but we 
need to solve the main question: 

   1) whether to engage in long-distance
communication at all (in principle, this question can be put 
this way: Do we need quickly new prog and toys??)


   2) Do you consider possible (in general)
City Point creation, or you think that this lichoe everyone's 
business? 

P.S. It is possible that all that is written here
appears to be quite delusional and disconnected,
but I think you understand the basic problem
and be able to comment on it.
