1. - INTRODUCTION
1.1 Some features
Opus Terminal is mainly designed for communicating with the BBS
program OPUS. It correctly interprets all escape sequences, including
colour, conforming to ANSI/VT100 or the special OPUS protocol AVATAR. It
will use blitter if present or directly address the screen memory in
terminal mode, thus making screen redraw very fast even with high speed
modems. Opus Terminal has a built in translation table which allows for
correct interpretation of language specific characters.
1.2 Hardware requirements
You need a Atari ST with a SM124 monochrome monitor or equivalent.
Any memory configuration above 500K will do. The program has been tested
with TOS 1.0, 1.2, 1.6 (STe) and 2.0. It will probably work with TOS
1.4. You also need a modem.
1.3 User support
This program is free. You may use it at home for your own
enjoyment. You may also give it to friends or upload it to a bulletin
board system, but only as long as all files are included and AS LONG AS
NO FEE IS TAKEN IN EXCHANGE. The use of this program in a business or
corporation is granted only under special license agreements with the
author.
If you enjoy the program and decide to use it please send the
author a postcard as a tribute to his programming effort. You may also
receive the latest version of Opus Terminal by sending an empty
formatted diskette in a self addressed envelope to the author, please
supply enough international reply coupons to send it back. All bug
reports and suggestions are welcomed. The address can be found in the
program.
1.4 Disclaimer
The author takes no responsibility to whatever happends when using
Opus Terminal. You use it at your own risk. The program has been
thoroughly tested and if the program turns your computer into a toaster
or vice versa, I'm surprised and indeed very sorry.
2. - USING OPUS TERMINAL
2.1 Modes of operation
Usage of the program is divided into two modes, menu and terminal
mode, you switch between them by pressing <Help>. After startup you
enter menu mode. Everything not concerning on-line typing and reading is
done here. Terminal mode is used when you want to write something
directly to your modem or when a connection to another computer is made.
In terminal mode you find a information line at the bottom of the
screen:
________________________________________________________________________
OPUS Terminal | Ansi | _______________________ | | 00:00:00
------------------------------------------------------------------------

| | |
V | |
(last message from modem, ex: CONNECT 2400)
| |
V |
(reserved for expansion)
|
V
(time on-line since connection)
You can switch between the modes while receiving, since incoming data
from the modem is buffered in a 8 Kbyte buffer. Remember that 8 Kbyte is
a lot more than a full screen.
The clock will measure time from the moment your modem sends the
signal CD (Carrier Detect). Some modem cables exclude this wire, with
the obvious result of a non working clock.
2.2 Basic preparations
Before using Opus Terminal as a terminal you must configure some
settings. All settings can be found under menu item "Settings":
"RS232"
Set the correct transmission speed between your computer and your modem
by selecting the appropriate button. Further you must select the
characteristics of the transmission: Flow, parity, number of data bits
and number of stop bits. Those charactersistics depend on the computer
and modem setup on the other end of the line.
"Terminal emulation"
Incoming escape sequences are always correctly interpreted whether they
are ANSI or AVATAR. However you must select the appropriate mode for
Opus Terminal to interpret the non-ASCII characters of the keyboard; you
choose if you want to send ANSI or AVATAR sequences. AVATAR is a lot
faster than ANSI/VT-100. You must also select the way the screen will be
redrawn in terminal mode; either use your blitter if you have one or if
not use the fast built in direct memory access ("CPU") mode.
When automatic Z-modem is on, Opus terminal will automatically
invoke Z-modem download at the request of the computer you have made a
connection to.
Please remember that ALL parameters found under "Settings" can be
saved in a special file under "File" -> "Save settings" for later
recall. When Opus terminal is started the file "OPTERM.DAT" will be
loaded as default. You can also make a setting for every phone number
(see Dialling).
2.3 Dialling
To dial a number you enter menu "Function" and click on item
"Dialer". A dialog box containing names, phone numbers and some
additional data will open. To make a call you simply select a name with
the mouse and press the button "Dial". The program will then turn into
terminal mode and try to make a connection. Leaving the dialog without
making a call is done by pressing "OK". To change or add a number you
select a name and press the box "Edit". You will now be able to change
the following:
name - Simply the name of the person, BBS or mainframe that you
want to store. Ex. "R. T. Nixon", "Ragnarök BBS", "CIA".
phone number - The dial string of your modem followed by the phone
number. If your modem is Hayes compatible the dial
string will probably be "at dt". Ex. "at dt 90510".
Please consult your modem manual for the correct
dial string.
setting - Every number can have its own settings file which will
be loaded every time you make a call, thus making Opus
terminal adjust itself correctly for different numbers.
Of course you can use one settings file for many
numbers. Ex. "SETTINGS.DAT", "JOHN.DAT", "NORMAL.DAT".
reset -
init - For every name there is a specific phone number and
setting. This is however not true to "reset"
and "init" which are the same for all numbers. Before
every call a reset and a init string will
