SuperMorse Version 1.05 CW Program Documentation
-------------------------------------------------

THIS PROGRAM IS WRITTEN FOR THE IBM PC, XT, OR AT COMPUTERS (OR
EQUIVALENT) WITH AT LEAST ONE SERIAL PORT. This program was written for color
systems but should operate properly in monochrome, it just won't look as good.
This program is SHAREWARE and as such is owned by Power Mountain
Systems. If you use the program you are required to register it. Registration
is only $25.00. If we have upgraded the program you'll receive the latest
version upon registration.
If you have purchased the PMX-200 (or an equivalent product) from Power
Mountain Systems then you are already registered, and have the latest version.
If you see a newer version and have already registered with us you have our
permission to use the newer Shareware version without registering again.
The PMX-200 is a device to interface between your computer and your
short wave receiver. It allows you to decode very weak CW & RTTY signals. You
can read more about this project in the April/May 1990 issues of Radio-
Electronics. Current pricing and more up to date information is available if
you write to us at the above address.
This program may work well on other CW systems but we obviously cannot
know how your equipments' RS-232 port may be wired. We also cannot guarantee
that the interface you're using is adequate. Noise immunity is critical for
good CW performance, and software can do little to compensate for hardware
deficiencies.
CW output to the interface from the computer is sent via pin #20 (on a
DB25 connector). CW data from the interface to the computer is sent via pin #8.
Pin 1 & 7 is wired to ground. Voltage levels are RS-232 standard.
OPERATION
=========
The first time you run this program you'll need to run the speed test
option in the first menu. After that you can just go right into the program
(option 'A') and get started.
After the delay is calculated a delay number is stored as Suprmors.cfg.
The program starts at 25 words per minute and in transmit mode. When a
key is hit a window will pop up and ask you what port you're using. After that
you're ready to transmit or receive CW.
Keyboard commands are as follows:
----------------------------------------------------------------
[ = go to receive mode from transmit
] = set new speed in wpm
{ = set new Com port ( 1 - 4 )
} = end session and go to DOS
+ = increment speed by 1 WPM
- = decrement speed by 1 WPM
/ = allows you to select a user message to send
For large changes in speed you can use ']' and for small changes use
'+' and '-'. After changing speed you'll be back in receive mode automatically.
To start transmission all you do is start typing. You'll see that your
cursor moves to the transmit window. You'll hear a beep when your keyboard
buffer is full. With a little practice you'll get used to how far you can get
ahead.
As each letter is sent it is displayed on the screen.
There are 7 user messages that you can set up and select from. "CQ.MSG"
is a text file you can create with a text editor or by using DOS's 'copy con'
command. "CQDX.MSG" is created the same way and it's use is obvious to a HAM.
"EQUIPMNT.MSG" can be a list of your equipment that you may want to tell others
about. "QTH.MSG" is a little about where you are, etc. "MESSAGE1.MSG", and
"MESSAGE2.MSG" are messsages that you can set up for your own needs.
Good Luck, and have fun! Please pass this program and this
documentation around in unaltered condition.

UPGRADE HISTORY
---------------
Version 1.05
============
Bug fix! Transmit routine was operating at a higher speed than the
receive routines center of operation. Receive was speeded up and now the
program works very well.
When changing to receive a character was being sent inadvertantly.
This has been remedied.
Version 1.04
============
This version puts you back into receive mode automatically after a
speed change.
Version 1.03
============
This version includes a much improved cw decode algorithm, and it
decodes much better.
Version 1.02
============
This version allows you to send a prewritten user message by typing
'/' on the keyboard and selecting the desired message from the pop up menu.
Version 1.01
============
This version raises the speed limit from 31 wpm to 52 wpm. Windows were
altered some to increase speed of operation. Windows now have a border and are
labeled.
