1/ Screens (DOS version)
------------------------

Four screens are available :

F1 : program
F2 : console
F3 : terminal (still not implemented yet)
F4 : full monitoring screen

2/ Memory (DOS version)
-----------------------

DxNet v3 is able to use XMS, EMS, or virtual memory (it is realised through
use of a temporary file placed in the the TEMP directory).

3/ Switch (DOS version)
-----------------------

DxNet needs either G8BPQ switch or Pc/FlexNet kernel.

4/ directories and files
------------------------

* All binaries files are stored in dxnet\system\bin\ directory.

5/ commands
-----------

Just a few numbers of commands are available in this ALPHA version. Please
look at the DxNet 2 doc file to get help using these commands.

SHow/Announce
SHow/CLuster
SHow/Configuration
SHow/DX
SHow/LANGuage		(give a list of the available language)
SHow/MEMleft

SET/Here
SET/HOME
SET/LANGuage		(set a language)
SET/LOGs
SET/LDEFault		(set the default language)
SET/LOCAtor
SET/NAME
SET/NOde		(used in place of DXNode command, see below)
SET/NOHere
SET/QTH
SET/SSID
SET/SYSop

Announce
Bye
Connect			(used in place of DXConnect command)
DISConnect/n		(disconnect the channel n)
DISConnect/ALL		(disconnect everybody)
DX
Information
PIng
QUIT			(exit)
Quit			(user command, same as Bye)
SHUTdown		(disconnect everybody and then exit)
Talk


SET/NODE
--------
Add "+" before a call you want to add, or "-" before a call you want to
remove.

Exemple : SET/NODE +F5MZN-3 +F6HPP-3 -F5OAH
	  will add F5MZN-3 and F6HPP-6 to the list, and remove F5OAH

6/ Languages
------------

DxNet is able to speak different languages. Messages are stored in LANGn.TXT,
while HELP messages are stored in HELPn.TXT, where n is the file number.

Both LANG1.TXT and HELP1.TXT are the default language files but it may
be changed by the sysop using the command SET/LDEFault.

Up to 10 languages are supported (LANG10.TXT and HELP10.TXT).

symbols :	%D	Date 'DD-MMM-YYYY'
		%d	Date 'DD-MMM'
		%H	Time 'HH:MM'
		%I	user's name
		%l	user's language
		%O	call of DxNet
		%o	call od dxnet without ssid
		%U	user's call
		%u	user's call without ssid
		%0-%9	temporary symbols


7/ \SCRIPT directory
--------------------

Script files (.FWD) use nearly the same format than the one of DxNet v2,
except "+", "?", "#" which are now optionnals. The # field still don't
work yet.

Config files (.CFG) are used to set different hops count for the protocols
which are coming IN or OUT, and to define some special sets for the
link as well. By default, all protocols are set to 99 and all sets are ON.
These files are optionnals.

		Function		Command		Protocol
		Talk			Talk		PC10
		Dx info			DX		PC11
		Annoucement		Announcement	PC12
		Add/delete user		USER		PC16 PC17
		Add/delete node		NODE		PC19 PC21
		WWVinfo			WWV		PC23
		DX/WWV merge request	MREQuest	PC25
		Dx merge info		MDX		PC26
		WWV merge info		MWWV		PC27
		Mail forwarding		MAIL		PC28 to PC33, PC40,
							PC42, PC43, PC49
		Remote commands		RCOMmands	PC34, PC35, PC36
		User info		UINfo		PC41
		Remote DB request	DATAbase	PC44 to PC48
		Update user count	UCOunt		PC50
		Ping			PIng		PC51


		Incoming protocol sets	[in]            Following commands
							apply to the
							incoming protocols.
		Outgoing protocols sets	[out]		Following commands
							apply to the
							outgoing protocols.

		CluLink	permission 	CLUlink on/off  Allows or not
							CluLink protocol for
							that link.

		Example (F6BEE.CFG)
		-------------------

		clulink		off
		[in]
		user		4
		node		4
		mail		off
		rcommands	off
		[out]
		user		4
		node		4
		mail		off
		mrequest	off
		mdx		off
		mwwv		off
		mail		off
		rcommands	off
		uinfo		4
		database	off
		ucount		99
		ping		on

8/ External commands (extcmd directory)
---------------------------------------

You can put programs (.EXE, .COM, .BAT) in this directory. Each time an
user type a command, DxNet look if its exists in the \extcmd directory.
If it does, the program is excuted instead of an existing command of
DxNet if any.

This allows the sysop to create new commands, on to redefine existing
commands of DxNet.

If you want to create, say, the command TEST : put TEST.EXE or TEST.COM or
TEST.BAT in \extcmd.
If you want to create, say, the command SH/SOMETHINK : put SOMETHINK.EXE or
SOMETHINK.COM or SOMETHINK.BAT in \extcmd\sh.

9/ Database
-----------

Local databases are support. See the manual of the version 2 (except for the
file which is now called SYSTEM\LOCAL.DAT).

Database updating is now allowed if it has been set in SYSTEM\UPDATE.DAT
file as following :

	UPDATE_CMD1	DATABASE_CMD1
	UPDATE_CMD2	DATABASE_CMD2

For example, you want to allow users to update the database QSL_NEW.FUL. The
command to search this database is SH/QSL (defined in local.cfg). Put the
following line in SYSTEM\UPDATE.DAT

	QSL		QSL

The two fields are basically the same.
