- SET/WWFilter OC was rejected. Fixed. Tks IK5ZUK.

- WW filter was not properly initializated for DxNet console. Fixed. Tks
  IK5ZUK and LA3WAA.

- Serial output buffer of the direct COM port access (DOS version) overflow
  problem fixed. Tks JA3BOA.

- Some BEEPs wasn't suppressed in talk messages even if SET/NOBEEP was
  activated. Fixed. Tks LA3WAA.

- Fixed a bug in the SET/WWFilter command used on the console F2. Tks LA3WAA.

- The low G8BPQ buffer count is now watched every 30 seconds rather every
  minutes (see release 3.1). Tks OH6NJ.

- Added the sysop command MEDIT. MEDIT is a basic text file editor, which
  can be used to edit small files (up to 255 lines).

  Syntax   : MEDIT <filename>
  Commands :
	#      : set the line # as current line.
	D      : delete the current line.
	D#     : delete # lines from the current line.
	I<str> : insert a new line <str> before the current line.
	WQ     : write (save) file and quit.
	E      : exit without saving.
	/<str> : put the string <str> in place of the current line.
	*<str> : put the string <str> at the end of the file.
	?      : show this help file.

- Added the new sysop command "DOS" (DOS version of DxNet only). This
  command opens a DOS session, where the following DOS command are available
  in :

  CD, DIR, COPY, MD (MKDIR), RD (RMDIR), DEL, MOVE, MEM, REN (RENAME),
  TYPE, RUN, GET, PUT, MEDIT.

  - RUN can be use if you want to execute any other command, like a batch
    file. Use it at your own risk, knowing the DOS session is only able to
    manage programs wich use the standart input/output (ie don't run EDIT).

  - GET works like the TYPE command.

  - MEDIT can be used to edit a file (see MEDIT section in this file).

- DX/WWV merge protocols (PC25, PC26, PC27) supported.

- Added to commands to set up the automatic merge request during the
  initialization sequence :

	. MRDX  <DxCount>
	. MRWWV <WwvCount>

  Add these lines in the config file (.cfg) of the adjacent cluster you
  want to request to :

  -- IK5ZUK.CFG --
  clulink off
  mrdx	  5
  mrwwv	  2
  [in]
  ...
  ...

- Rewrotte the whole WWV functions to get a more efficient code.

- Rewrotte the whole DX functions to get a more efficient code.

- Fixed a bug in clulink protocol.
