The Data Retransmission Engine Release Log

1/29/97	- Released Ver 1.0
1/30/97 	- Released Ver 1.01
		- Minor cosmetic changes on start-up.
		- Changed Tx Stop Bits to 2 in retrans.ini for improved 
	  	reliability on weak signals. 
		- Fixed a bug that caused .txt products with filenames <12 
	  	characters to be mistaken for graphic files by receive window.
		- Changed compression routine to limit files packed to those with 
          	.txt extension for later compression to .zap file.
2/03/97	- Released Ver 1.02
		- Changed file distribution routine to allow .nws and .zip files 
	  	to fall through all lists instead of being forced to the 
	  	\wnoderxt\decomprs. (.zap files are still forced to decomprs.)
		- Added logging of all packets and CWID sent. Logs are in \wnodertx
	  	and are named logDDMM.txt where DD is day and MM is month.
		- Changed program startup to load unsent files in \retrans directory
	  	on startup into the midpri send schedule.
2/5/97  	- Released Ver 1.03
		- Limited the number of files that can be combined into one
	  	compressed file to between 10 and 200. Less than 10 files benefit
	  	only slightly from compression while greater than 200 files
 	  	create a file that is too large to transmit reliably.
		- Added a checkbox to the Low/Compress setup tab that allows
	  	files to be sent from the \wnodertx\compress directory when there
	  	are no other files awaiting transmission. With this box unchecked
	  	files are accumulated in the \wnodertx\compress directory until a
	  	compressed file can be made. 
3/10/97 	- Released Ver 1.04 
		- Rearranged the send boxes to allow the display of full filename.
		- Changed receive engine to limit valid filename to the characters
	  	"A"-"Z", "0"-"9", "." and "_" . Any other character is considered
 	  	a receive error and the block is discarded.
		- Added code to ignore a file that is locked when it is placed in the
  	  	\highpri, \midpri or \lowpri directories until it is unlocked. 
5/31/97 	- Released Ver 1.05
		- Changed state of RTS to properly power comport-powered modulators.
		- Modified error-handler to disregard any incomplete file or any zero
	  	length file that is moved to \highpri, \midpri or \lowpri directory.
6/13/97 	- Released Ver 1.06
		- Changed timer for compression of multiple text files to fire every 5 minutes.
		- Changed timer for purging of old files to occur at the top of each hour.
		- Net results of changes is that the transmission no longer stumbles at the
	 	top of each minute on computers with slow disk access. 
7/2/97  	- Fixed a bug that created multiple entries occasionally when files
	  	were externally transferred to directories.
7/17/97 	- Changed receive routine to leave tracking files on the \rxtrack directory
	  	rather than delete them after files are received. This eliminates the
	  	problem with files that are transmitted twice being treated as a new file
	  	when they are received. Files will purge on purge cycle.
7/30/97 	- Changed the compress routine to move compressed files to the routine 
	  	window after compression. This allows multiple large graphic files to be 
	  	stacked in the Low/Compress directory without slowing the transmission of
	  	compressed files.
9/9/97  	- Renamed the Setup Purge tab to Setup system to accomodate additional
	  	system options (below).
		- Added the ability to select the filler file to the Setup System Menu. 
	  	This file will be transmitted repeatedly to keep the system active when 
	  	there is nothing in the transmit que. The default on a newly installed 
	  	system is c:\wnodertx\mrcfiles.txt. If this entry is left blank, or the 
	  	file specified in this entry is not available, the Retransmission Engine 
	  	will stop transmitting and unkey the transmitter (when used with the 
	  	MD-201A modulator) when there is nothing in the transmit que. The Morse 
	  	ID will continue to be active and identify at the ID frequency selected 
	  	in the Setup Morse ID tab.
		- Added 'PTT to Data Delay' to Setup System tab. This setting determines the
	  	delay after PTT is activated, to allow receiver squelch to deactivate, before 
        	data begins to be sent. 
		- Added a Log checkbox that controls the logging of sent blocks and Morse
	  	ID to c:\wnodertx\logMMDD.txt. Note that the logs created by this option
	  	are not automatically deleted. If you elect to log the transmit activity
	  	of your system, You should manually delete the files occasionally to 
	  	prevent your hard disk filling.
2/11/98 	- Released Ver 1.11
		- Fixed a bug that caused the discard list to be processed before Immediate,
		Routine, or Low/Compress directory. Order of processing is now:
			- Immediate
				- If a file matches a search key in this list, it is moved to 
				the \hipri directory for immediate transmission on a FIFO basis.
			- Routine
				- If a file matches a search key in this list, it is moved to 
				the \midpri directory for transmission on a FIFO basis after all 
				files in the \hipri directory have been sent.			
				- Low/Compress
			 	- If .txt files are specified, they are moved to the \compress
					directory for later processing. The files are transmitted as
					specified by the Compress tab of the Setup Screen.
					- If anything else is specified, it is moved to the \lowpri
				  	directory for later transmission.
			- Discard
				- If a file matches a search key in this list, it is moved to
				the \discard directory.
			- Routine
				- If a file falls through all of the lists above, it is moved to
				the \midpri directory for transmission on a FIFO basis after all 
				files in the \hipri directory have been sent.
