900913 -Version 1.0

901004 -File menue: 'RX logfile' now opens a dialogbox for 
	logfile selection. Standard filetype is .LOG.

901017 -New menue 'Qth': calculate distance and direction
	from qth locators. The results are displayed and assigned
	to the texts 'distance' and 'direction'.

901101 -Version 1.1

901125 -New display function "SPECTRUM".

901204 -Converter schematics changed: OP-AMP output now connected
	to DSR.

901205 -Version 1.2

901212 -TX speaker control changed to smooth out tone.  Timer 2 was
	reprogrammed for each and every bit send.  Now the timer 2
	is only touched when absolutely neccessary.

       -Number of stopbits changed from 2 to 1.5.

       -QTH calculator: Field QTH2 is now selected on activation.

       -The startup value of the audio center frequency can now be set 
	from a configuration file using the command "SET AFCENTER <x>",
	where <x> is an integer between 500 and 2000.

       -The startup value of the audio frequency difference between the
	mark and space tone can now be set from a configuration file 
	using the command "SET AFSHIFT <x>", where <x> is an integer 
	between 25 and 1000.

901216 -Idle character transmission can now be controlled using the
	"Diddle on/off" function on the "Keying" menue.

       -The startup state of the "Diddle" flag can be set from a config
	file using the "SET DIDDLE ON" or "SET DIDDLE OFF" commands.

       -Config files can be selected and processed "on the fly" using
	the "Load .cfg file" item on the "File" menue.  This is handy,
	if the next qso partner is from a different country and you
	want to switch to a different set of standard phrases.

       -ALT-X will terminate the program.

901222 -Prototype of callsign decoder added.  Database needs update.
	Select item "Callsign" on "QTH" menue to activate function or
	hit ALT-C (this may change).

       -Parser for config files changed. Token "" is now recognized as
	a NULL token. This is handy for "undefining" text elements
	from config files.

901228 -Added line to "SCOPE" function to show current center frequency
	for precise tuning.  Green color on color displays, white
	on monochrome.

910109 -Added TXDELAY. This is the minimum delay required for the 
	transmitter after activating the ptt line. Can be set from a 
	config file using the "SET TXDELAY <x>" command, where <x> is 
	the number of milliseconds to wait.

       -Added TXWAIT. This is an additional delay until the first 
	character is sent, just to give your qso partner a chance for 
	fine tuning to your signal.  Can also be set from a config file 
	using the "SET TXWAIT <x>" command, where <x> is the number
	of milliseconds to wait.

910128 -Added help text for SPECTRUM function.

910211 -Added preliminary version of WORD entrymode.  Toggled by
	control-W from the RTTY window.

	Rules for WORD entrymode:

	When the SPACEBAR is hit the characters between the current
	cursor position and the first blank to the left of the cursor
	will be send to the TX buffer, followed by a blank. 

	When the ENTER key is hit the characters between the current
	cursor position and the first blank to the left of the cursor
	will be send to the TX buffer.  In the next step all characters
	from the current cursor position to the end of the line will be
	send to the TX buffer, ignoring trailing blanks.  Finally the
	usual carriage-return/line-feed sequence is send. 

	If this explanation leaves you in total confusion then simply
	give it a try. 

	Please note that word-wrap is not yet implemented for WORD mode. 

       -Added preliminary version of transmit monitoring.  Toggled by
	control-P from the RTTY window.  Characters are echoed to the RX
	window on transfer to the TX buffer.  This will probably change
	in the future!

910213 -Added word-wrap for WORD entrymode.

       -Added help text for RTTY, TUNE and SCOPE display.

910216 -Added line drawing routines to speed up SPECTRUM display.

910217 -Changes to TX monitoring: characters send to the TX buffer are now
	displayed on the line separating the RX window from the TX window.
	The P option, controlled by control-P, is now enabled on startup.

910307 -Help text for RTTY updated.

910308 -Version 1.3

910503 -Title corrected for "Load Config File" file select box.

910514 -Added PADELAY. This is the minimum delay required by the PA to switch
	to TX mode. The PTT line is active but the speaker is still turned off.
	PADELAY can be set from a config file using the "SET PADELAY <x>"
	command, where <x> is the number of milliseconds to wait.

       -Added capacitor to transmit circuit schematics to remove DC offset
	on the mic input.

910519 -The size of the receive buffer can now be set using the
	"set rxbuffersize <n>" command.

       -INSERT mode no longer turned off when moving to another line.

910520 -The size of the transmit buffer can now be set using the
	"set txbuffersize <n>" command.

910521 -The "Send text" function now displays all texts in alphabetical order.

       -Texts for shift-f1 - shift-f9 keys renamed from SHIFT_Fx to SHIFT_F0x.

910522 -TX monitoring: transmitted text is now displayed in the RX window
	and is written to the log file.

       -Control-HOME and Control-END now scroll the RX window one page
	backward and foreward.

       -Control-LEFT and Control-RIGHT now scroll the RX window one line
	backward and foreward.

910523 -The number of lines in the RX window buffer and in the TX window
	buffer can now be set from hc.cfg using the commands
	"set rxwindowlines <n>" and "set txwindowlines <n>".

910530 -Added "Send text file" function to FILE menue.

       -PAGE-UP and PAGE-DOWN now works for TX window.

910531 -Control-D sends date and time. Use \d in predefined texts.

       -SCOPE and SPECTRUM display can now be stopped for examination
	using the ENTER key or the right mouse button.

910602 -Added End-Of-Text marker to automatically switch back to
	receive mode. The eot character can be specified in a .cfg
	file using the "set endoftext <n>" command. See hc.cfg for
	examples.

       -In predefined texts \e will be replaced by the currently 
	selected End-Of-Text character.

       -Added item "External Converter" to "Keying" menue.  If this
	option is enabled, a mark/space signal from an external modem
	is expected at the CTS pin of the COM port. Note that the
	miniconverter is still required. There will be no reception
	if it's not there or has no input signal.
	(De)Activated also by ALT-F9/ALT-F10 any time (this may go away).

910608 -FSK output now available on DTR pin during transmit. 

910609 -New menue INFO added.  

910630 -Added "Define 'CALL'" and "Define 'NAME'" to TEXT menue for
	fast (re)definition of your qso partners call and name.

910706 -There was a delay during allocation of the RX and TX windows
	on first entry to the tty screen. For a few seconds the display 
	looked like the program had crashed.

910707 -Added "DOS shell" command to FILE menue.

910810 -SPECTRUM function:
	'*' toggles line/dot mode, 
	'+' toggles 'shadow' (color displays only)

       -SCOPE function redesign for more accurate timing on slow XTs.
	PAGE-UP/PAGE-DOWN keys increase/decrease sample rate.

910815 -The maximum transmit line length can be set from a .cfg file 
	using the "set txlinelength <x>" command, where <x> is the
	number of characters per line.  See hc.cfg for an example.

910816 -Added support for SuperVGA text modes.  Some VGA cards have
	special text modes e.g. 80x60 or 132x44.  Activate desired mode
	before starting HamComm.  Most cards come with a utility program to 
	do this.  Only the modes where the video display buffer starts at
	segment B800 are supported. 

910818 -SCOPE function:
	'+' toggles display of the decoded mark/space signal. 
	Default is off.

910820 -Added experimental mode for morse code reception.  
	Activate via MODE menue or hit F2.

910904 -Added qso counter for use in contest. There are three new 
	selections on the TEXT menue to
	 - set the counter,
	 - send the current value or
	 - advance and send.

	The send functions can also be called from predefined texts
	using the \# and \+ sequences.

910910 -Morse code reception improved.

910914 -Added TX routines for CW mode.  Special characters:
		'@' = -.-.-	KA
		'#' = ........	ERROR
		'$' = ...-.-	SK

910923 -Name of BAUD menue changed to SPEED.

       -Added WPM selection to SPEED menue.

911006 -Added 'Automatic Frequency Control' (AFC) for RTTY reception
	(ALT-F7/ALT-F8 or KEYING menue).  AFC is active in RTTY modes 
	only (not CW) when the RTTY screen is selected.

911014 -CW transmit: corrected coding for characters 'W' and ')'.
	Added character '_'.

       -If the CURSOR-DOWN key is depressed while the cursor is on the
	bottom line of the TX window, the TX window is now scrolled up
	one line.  The top line is lost, the bottom line is empty.

911015 -Version 2.0
