Letters - Letter from Kharkov on the "knowledge" in the world Hayes modems. Wiring diagram domestic HAYES-modem.

                 LETTERS



              Hi, Alex!


  Not just a hello, and hello to all
spektrumistov Kharkov! :) That's got
37 th Newskah and decided to write you a little bit
about our "knowledge" in the world Hayes modems.
:)


  It all started a year ago: there was a first
spektrumist with Hayes modem - Gregory Shepelev, he also 
released a wiring diagram modem to the spectral (very simple) 
and terminalku ... True terminalkoy it is now difficult call, 
but then 32 characters per line and calls Xmodem'om - it was

not bad ...


  A little later, the modem is still a good buy
man (now my friend), Victor Soroka
(VIC). Since the modem was external, he developed his scheme of 
COM-port and began to write a new terminalku.



  Next was I bought an internal
FAXMODEM2400/MNP5/V42BIS, and connected it
scheme Shepeleva (about VIC'a I did not
knew). After some time I also began to
write terminalku, whose capabilities
there was more: 64 characters per line, reception / 
transmission protocols Xmodem/Xmodem1k / Ymodem/Ymodem1k ... 
But, it completed yet at 60 percent, I met Victor and learned 
that he has finished terminalka with all the above charms, and

also supports ANSI graphics -
MELON1.0.


  The main feature of Mellon is
that it uses the hardware video mode
Speck - 512X192 / 2 colors (the scheme was not
long ago in one of the "online"), which allowed not straining 
to work with multiple PC BBS - they have the same 85 characters 
per line. ;)



  Well, of course, its to the term, I scored,
set himself 512X192 and away ...


  The farther into the forest - the wood is,
DISMASTER / X-Project, and AMP / X-Project is also
got a modem, the head of X-Project
Corp. - DR.Squizer - opened a BBS for the spectrum, on the PC 
though (like screws trailer - That's when we pohohochem;)!



  Terminalka Melon is currently being finalized and is 
accelerated Dismaster'om - already added receiver ZMODEM, 
transmitter gradually completed. In his plans - to build in 
Melon program "mailer," Well, to his "pointovskuyu" mail merge.



  I am currently engaged in software processing Fido-mail, has 
already written chitalschik PKT-mail format that's left to do 
message editor with subsequent conversion in MSG format.



  All of our designs for modem use video mode 512X192! And what 
you want, unless of course Hayes will be on the move! ;) 


  Speaking of modems: once in the echo
ZX.SPECTRUM read such a stupid statement that Speck did not 
pull the modem at 14400 ... Brad, however, I'm 3 days ago 
bought a UMC14400, and? All ok! "Pulls" and without TURBO

mode! True port is locked at the 14,400, too ...


  Very interesting, and have achieved / done
"Your" coders in terms of software for Fido?


  Below, give the wiring diagram of the internal modem, if 
somebody interested? (All signals given by the Pentagon 
diagram). 


                That's it!

 If you want to write, then the gate:

   Bye!

   Sincerely, Eugene aka ZMAN / X-Project
