ZXNet - On the use of a modem "Allegro."
ZXNet
(C) ALEX
Hello, dear users and system operators!
In this article I wanted-a little bit to go through several
Questions have been raised over the past three weeks as in the
correspondence network ZXNet, and in computer magazines.
1. Question the use of modems on the basis of the scheme
"Allegro" and the feasibility of a BBS on the ZX-Spectrum
platform was raised in St.Petersburg journal ZX-Format N 3.
What can I reply to the author? I will answer the facts of
our lives:
- Programs for the ZX takes up much less space than a
similar program for the IBM PC (we are talking about games and
system programs). So the two drives, the server is enough.
Who works in our network - can attest to this.
- The author probably had an old program to support the work
of modem times he refers to the low exchange rate. Yes, speed
somewhere 2400-2600, but try on our phone network work faster!
PC-kovsky HAYES-modem over 14,400 works in 90% of cases at 9600
or less (this applies, of course, MGTS).
In the least, ZX-Format is transmitted using
"Allegro" for 35-40 minutes, and the modem itself is 10-30
times cheaper HAYES-modem!
Yes we still have practiced the use of packers to transfer a
large volume of programs and data.
- Not all users have the opportunity to buy a PC - it is
and gave an impetus to the creation of ZXNet - network,
operating on a platform of the Spectrum, but with "gateways" to
access to other networks. From a lack of exchange rate no one
has yet suffered.
2. Question concerning the mayhem MGTS has been raised by
users ZXNet, Dorval until last year (1995) correspondence
FIDONet and up to last year's computer publications.
Here the theme a little overlap with the first question.
- The fact that, indeed, MGTS has the right (confirmed
legally) to catch a modem using a special instrument, scanning
from time to time telephone channels. In principle, this
instrument is designed to detect the fax. And because the scan
is done automatically and without recording the observed
exchange, it is not considered Wiretap Your negotiations.
Example:
You do not blame, for example, your LEDs
On the modem that they overhear your line?
So, dial-up users "Allegro" do not worry. The fact that it
is, in principle, and not just a modem. He works in a wider
band than HAYES-modem (that works at two frequencies with a
narrow stripe)! And just "Allegro" is perceived as a
conversation apparatus (... cool conversations throughout band
telephone channel!), not as a modem detection, or rather, not
in any way perceived!
By the way, why not connect "Allegro" (despite the fact
that the C-DOS uses one of the IBM-protocol) HAYES-modems.
- That with regards to the principles of FIDO, for example,
threatened, in case of infringement of the rights of users,
manual choke MGTS bunch of letters (about 5000 users and
operators of Moscow). Topics more is not the fact that someone
from the leadership of MGTS or their relatives are not on FIDO!
There, everything is under control.
Conclusion on the second question: as long as you personally
MGTS is missing, no necessary to raise howl and excite other
network users. And then somewhere someone something read or
heard - and followed a flurry of indignant letters.
And if suddenly you really PBX naedet
- Then tell all the detailed facts and keep a written
notification from the telephone exchange. WE WILL FIGHT
TOGETHER!
3. At this point I want to appeal to new users who are only
going to or just bought a modem.
Nobody will allow an unknown person to "dig in his
pockets! "Most people understand this and leave information
about yourself.
But we have two more ghosts that pump with servers
full disk, and only the game, and nothing about himself is
reported. Numbers of users are marked as long as the phone book
question marks. A System Operators ZXNet (ONLY) could have I
know, and home addresses.
