   INTerminal 1.06 Beta

__________________________________________


   Well, the first version came out.
Can immediately draw attention to the release date of the 
program and the date in the welcome menu. More than a year from 
the date of writing the first living version of this 
terminalki. Why passed so much time, and I terminalku

did not dare "to publish"? Reasons for this were several. There 
were many disputes in the Spectrum ehokonferentsii REAL.SPECCY 
about the "transfer" modems interrupts. The idea is certainly 
reasonable. Without interruption of high speeds on the modem 
will not reach. I'm talking about Haes modem, ie, those modems, 
which can be get connection speeds 14,400 or more. Especially 
because these modems have become affordable (around $ 15) and 
each year their price falls. 

   The first terminal program on the Speccy
not use interrupts from the modem. K
These programs include, for example, Melon. After the 
appearance of the scheme Kondratieff situation has changed. But 
I still thought this scheme due to incorrect use

nonmaskable interrupt (NMI) Z80. In REAL.SPECCY I suggested 
that yet later, it is necessary to rethink the people and come 
up with a proper system (the scheme) reception

interrupt from the modem. For example, you use the INT signal 
without compromising system whole. But! Most people simply 
refused to understand this problem. It is to understand! A 
similar situation was and AY-coprocessor connection: from the 
very beginning was brought to him "non-proprietary" frequency 
and still people are even software do not want to fix this bug. 
There are well appropriate phrase: "Aba as work." Well

also, perhaps, many people tend to make mistakes, to convince 
the others that way and necessary. And then after some

time still have to correct these
errors, only this time with others. Philosophy
philosophy, but the fact remains.
Only two (!) Supported the idea of human
INTa. Others make a "clumsy" placing on the NMI. The whole 
point is that under the scheme Kondratiev has been written 
software (terminalka, mailer), and a huge amount people (but 
not here in Kharkov! which is nice) collected under this scheme 
Haes internal modem. A software under INTovuyu scheme was not, 
although the scheme has already been (and what was on the 
scheme - dopaivaetsya two (!) details to those already 
collected scheme Shepeleva). And not once were attempts to 
alter the scheme so that the terms of the programming was easy 
to work with the modem. So I wrote a version of terminalki for 
INT interrupt. I have a lot of it tested the modem with UMC 
14400 zalochkoy Modem Port for 57600. Sorry that did not test 
the program at a high speed modem (due to lack of it) with 
zalochkoy port to 115200. But with such speed is necessary, as 
it seems to me to use the FIFO buffer modem. Although this only 
speculate. How does terminalka, For example, the modem 33600, I 
do not know. I hope you check it. I think as long as enough to 
philosophize and "dissolve" is already has long been bored with 
all the problems. Let us directly to practice. So, first

Schema refinement scheme Shepeleva. You will need a mounting 
wire, transistor KT315 (KT312), or similar, the resistance to 
1k, the soldering iron. Here's the scheme (if one can call a 
scheme ;-): 



   I drew a simplistic, I hope everyone will understand. The 
transistor is soldered directly to the line between the INT and 
GND DD55 and DD67 at the Pentagon 128. The rest is clear

and so. The only thing that can still be added to the scheme, 
so that resistance 2Kom between the earth and the B24 connector 
modem. But in general and so everything works. Unfortunately,

I wrote the program from just under the COM1 port.
He has an address # 38BF. Later in the program will provide for 
other addresses ports. About what will, see below.



   Now let us briefly about the program itself. So
As I longtime fan MELONa, then in his left terminalke 
bolshins6tvo functions with the same keys. There are some 
differences in the pointer (or cursor, and not [Q] and [A]), 
exit from the menu (press [SS] + [CS]), and so on. All of this 
is easy master and without a description. I'll tell you more 
about Some features terminalki. During the boot terminalki if 
you hold the key [SPACE] pressed, the configuration file 
terminalki CONFIGTXT not boot and thus do you see a "purified" 
option in the different sections of the menu. If the boot

in the usual way, we can see one of the
configuration examples terminalki. After
Welcome terminal will check the modem, if
it is not found, there will be a warning. Even if the revised 
scheme will not be collected, the terminal it will still run. 
Just you will not see response from the modem. Even be performed

modem commands. After the greetings menu
terminal initializes the modem with two
init-string with a pause of a second. These
line defined as Init1 and Init2 in [Modem Strings]. Ease of use 
is two init-lines, I think, justified and

convenient. Pause can be changed in the menu [Dial] -> [Setup]. 
One unit corresponds 0.02 seconds. This value of time (until

this version) applies to all delays in terminalke. In what will 
be introduced by different values for the main

routines, as is done in Melon.
After initialization, the terminal is ready. I must say that 
it's "crude" or say, Demo-version terminalki under INTy. So 
while using it you can only visual estimate of speed and 
usability as compared to other programs. Certainly say that at 
a speed of 14,400 compounds and zalochke port 57600 characters 
will not fly, "nirvana" as For example, in Melon. The top row 
shows the main modes of the program. Insensitive, speed 
zalochki port (CRAZY speed correspond to 115200 baud)

icon presence of carrier (Carrier Detect),
"Mill" work terminalki and selected
drive.

   We turn to the [Main Menu]. Off-Line, it is
interruption to the station. Or other
the words "hang up". And I did
interruption through the team, rather than hardware, as in 
Malone. This allowed a clear break in the relationship at any 
time for a few seconds (as opposed to MELONovskogo "hang"). 
Interruption works as follows: first given the sequence Escape 
(+++), then kept Pause (50), then given string "OnHook". They 
are all definable in [Modem Strings]. Init Modem in the [Main 
Menu] will do the same as when you start the terminal (among 
other things Init startup can be disabled in the [Settings]. 

   Next Menu [Dial]. This automatic redial on
selected numbers. You can directly enter the number of dial-up 
- [Dial Number]. Or choose from a table [Dial by

Table]. Option [Edit Table] allows you to edit the table 
numbers. For convenience, I especially combined phone and

comment to him. When dialing from the table
will be taken only the first eight characters
which is quite enough. In the [Setup] can
change the dial: Dial Time
- Standby time CARRIER signal when dialing. Usually in the modem
also has an option (usually 45 seconds), but I decided to add 
your Dial Time, to accelerate the process of dialing. Dial

Loop - the number of redial attempts. Pause -
setting time (usually 1 second, ie
value 50). Ring Loop - value for avtopodnyatiya handset modem. 
This will be discussed in Autoanswer. So, you have chosen

number from the table and hit the redial menu. It shows all the 
parameters of the dial, including responses from the modem. In 
order to quickly make an attempt peredozvona, click on [Enter]. 
To interrupt redial, press Break, ie [CS] + [Space]. After 
receiving the signal CARRIER terminal automatically returns to 
its main mode. Line CARRIER with all

rate parameters and the protocol is stored and displayed in the 
foreground. 

   Menu [Tokens]. Here you can change everything
Thong reserved for terminalki and
for the user. They are separated and are referred to [Modem 
Strings] and [User Tokens], respectively. In [Modem Strings] 
Dial, you can change the prefix, ie, command that precedes in 
the dialer. Icon "|" there should not be inserted. This icon

used as the [Enter], as well as in
Melon. Answer string is used for Auto Answer. It will be issued 
after receipt of ring signal, but at the hardware level,

ie not paying attention to the zero register your modem. In 
this string of possible input Any team (not just ATA |). In 
future versions of the terminal will be more flexibility to use 
this feature. Pro Thong Init1 Init2 and I have already spoken. 
Escape here Standard - "+++". In string OnHook need

insert command E1 modem, because mode
dialer used ATE0, therefore, after bond and did not use this 
command to display the echo from the modem You will not see. It 
is still a significant disadvantage in the terminal, which is 
(hopefully) will in future be overcome. 

   Menu [Settings]. There are a lot of functions not
work and left for future versions.
Mode of 512 points is not working, but I think I will continue 
to be released separate versions and 256pixels 512pixels Only 
Only. So it will be much more convenient from the point view of 
programming, and glitches will be less. Auto Init function 
allows you to disable / enable the modem initialization when 
loading terminal. Other functions are not Take no action.


   Menu [Disk]. Specially made to the disk. Here you can save / 
load CONFIG file (ie your configuration program). View the 
directory of the drive (the first 40 files). Or a detailed 
directory [File Parameters]. Option [Select Drive] changes the 
current drive, if you have more than one. Function Load 
Scenario is not yet available and will be implemented in 
subsequent versions. All disk errors, I tried to catch the 
program, but possibly will be glitches. If these are to be 
seen, please do not be lazy and tell what will

very grateful.

   In general, for now. Ah yes, the output from the terminal 
through a BASIC Graphics Mode, ie [CS] + [9]. Return back - 
RAND USR 30721. All other functions are absolutely

identical MELONu. [SS] + [Q] - clearing the screen and the 
cursor in the upper left corner. [SS] + [E] - Issuing code Esc. 
[SS] + [I] - mode of issuance tokens via [CS] + [SS], [Space], 
[Enter] and numeric keys. [CS] + [1] - Rus / Lat.

[CS] + [2] - Caps Lock. [SS] + [6] and [SS] + [7]
- Reduction and increase in speed zalochki
Modem Port.

   What to expect in future versions? First of all protocol 
support transfer files ZMODEM. Transition mode 512 points. 
Support LOG files. Also establishing a "Scenario, which 
introduces fast and interactive terminalki.

The possibility of this regime are inexhaustible,
such as the construction of simple BBS and postmen. Expansion 
of already existing functions, including support FIFO mode 
modem. Etc., etc. And something else ...



   If you will be noticed bugs and glitches in the terminal, 
please tell them about telephone 529733 in Kharkov, or FIDO 
address 2:461 / 1024.6 Vova Bakum.
