Thanks

Thanks to Ken Wolff, K1EA, for his help with the specification of the network
protocol and the code fragments to support it.

Trademarks
==========

Obviously, throughout the package and text, any references to CT(tm) are 
the trade marks of their owners, Harvard Radio, and of the owner/developer 
of CT (as far as I know) - Ken Wolff, K1EA.

Compatibility
=============

I built the program using TurboVision in Borland C++ 3.1. It seems to be
OK on most 386's and 486's - although there may be something out there 
that it may "hang" on. It should work on most things from an XT up, 
although I have not tried many other PC's. I have tested it under 
MS Windows 3.1 and didn't experience problems. It doesn't have much in 
the way of software requirements other than just having enough memory to 
run. 

Congest exects the serial ports to be the default IRQ's, that is IRQ 3 & 4
for COM1 through COM4. If you have something other than that, it may not
talk to the outside world.

CT 9 hasn't been tested against. I'm assured by Ken Wolff that nothing has 
changed so it should be OK.

Using Congest
=============

Run the program from the command line as you probably would normally. The
menu can be accessed by "ALT-C" or by "F10" and then "C". Use the cursor
keys to highlight a menu option and enter to select.

(1) Rate (F3)

The traffic rate can be adjusted by selecting the "Rate" menu option.
Use the cursor keys to highlight the rate you want and press enter to select
it. Escape always leaves the current dialog box without doing anything.

(2) Select (F4)

The traffic types can be selected from the "Select" menu option. The 
callsign which is used in some of the traffic can be changed and the numeric
network address (1-16) can also be changed. Be aware that if you try to send
data to another station with the same station number, then that receiver 
station will not recognise it.

(3) Port ...

The serial ports that congest uses can be adjusted using the "Port A" or
"Port B" menu options. The usual serial ports options can be found, with
the option to switch traffic sending on or off with the "Service Type"
radio button. By default, it is switched ON. It is possible to start traffic
generation but for it to not be sent to the serial port. So, make sure
it is on before you send traffic.

(4) Start/Stop (F2)

F2 starts and stops the generation of traffic. It always waits for the last
scheduled traffic before stopping.

(5) Leaving the program  (Alt-X)

ALT-X or "Exit" from the menu will end the program.

Misc
====

I have watched CT running at a cool 7500 QSO per hour rate for quite a while
when using congest!

The number in the lower right corner is the amount of memory left in the far
heap. Normally 200 or 300K free under most situations. If use see a 
dangerously low number, like 16K or so, the package has probably hung (or 
is about to) and will halt as soon as you leave the program since 
"command.com" cannot be loaded again.

Other network traffic is not logged or shown. For simplicity it simply 
discards it. So if another network station sends data you will not see it.
