2002-01-13 12:29  shane

2002-01-12 20:08  shane

	* TODO, console.c, intercom.c, intercom.h, pkthandler.c,
	userdefs.c: Added optional GSM compression.

2002-01-12 17:45  shane

	* TODO, console.c, intercom.c, pkthandler.c, userdefs.c: Added exec
	command to execute an external program.  Added cmd_call and
	cmd_hangup variables which are executed on incoming call and hangup
	respectively.  These are intercom commands not external commands so
	exec should be used for external commands.

2002-01-12 17:00  shane

	* Makefile.am, console.c, console.h, intercom.c, intercom.h,
	pkthandler.c, userdefs.c, userdefs.h: Added user-configurable
	variables with the set command.  Most things set from command-line
	can be set using 'set'.  New stuff as well such as setting of
	prompt, and auto-answer mode.  removed --silent switch from alias
	and use --verbose so silent is default.

2002-01-12 14:58  shane

	define a bit.  Set min reserves on iobuff's appropriately.

2002-01-12 14:48  shane

	* iobuff.c, iobuff.h: Make the number of bytes below which we don't
	free pages configurable.  Note: this is now 0 by default.  iob_read
	uses readkeep and delete.  iob_queue was ignoring allocated but
	empty pages.  Other small optimizations.

2002-01-11 23:21  shane

	* intercom.c: Remove audiologfile stuff for now.

2002-01-11 22:44  shane

	* configure.in, intercom.c, intercom.h, pkthandler.c: Drop threads
	yet again.  Since the recorder thread was an attempt to solve the
	click problem and it wasn't related, we don't need them for now.  I
	may have to put them back but don't intend to until it is
	necessary.

2002-01-11 22:10  shane

	* intercom.c: Finally got audio clicking problem fixed...
	Hopefully.

2002-01-11 12:29  shane

	using GETxSPACE.

2002-01-11 01:07  shane

	* configure.in, intercom.c, intercom.h, iobuff.c, iobuff.h,
	pkthandler.c: Use threads for recording and sending audio.

2002-01-10 22:36  shane

	* logoss.c: Small preloaded shared library for OSS debugging.

2002-01-10 22:34  shane

	* intercom.c: More audio improvements.

2002-01-10 16:07  shane

	* console.c, intercom.c, intercom.h, pkthandler.c: Added ability to
	log audio data to a file.  Further audio improvements. (clicking
	problem still remains)

2002-01-08 13:56  shane

	* console.c: Limit command-history to 100 entries.

2001-12-17 15:18  shane

	* TODO, console.c, console.h, intercom.c, pkthandler.c,
	pkthandler.h: Don't add commands from rc files or alias expansion
	to command history.  Try to prevent alias and command loops.  Add
	ability to send text messages between users.

2001-12-17 14:17  shane

	* protocol.h: added PKT_TYPE_USRTEXT packet type.

2001-12-17 02:31  shane

	* console.c: And yet more alias work.  Now extra data after an
	alias is included in the expansion.

2001-12-17 02:21  shane

	* console.c, intercom.c, intercom.h, pkthandler.c, protocol.h:
	Remote fragment size from protocol and determine automatically.

2001-12-17 01:15  shane

	* console.c: Further alias fixups.

2001-12-17 00:26  shane

	* TODO, console.c, console.h, intercom.c: Added ability to read rc
	files automatically and via the CLI.  Removed CLI command
	shortcuts.  Added alias support which replaces shortcuts removed
	above.

2001-12-16 22:31  shane

	* intercom.c: Improve capture reading code.

2001-12-16 21:11  shane

	* intercom.c: Make the UDP packet size definable.

2001-12-16 20:14  shane

	* iobuff.c, iobuff.h: Fix several bugs and improve iob performance
	by not dealocating the 1st page.

2001-12-16 19:14  shane

	* configure.in: Check for ncurses for as it appears needed by some
	broken readline installations.

2001-12-16 16:38  shane

	* configure.in, console.c, intercom.c, intercom.h: History file is
	~/.intercom.history rather than ~/.intercom/history.  Fix bug where
	the USER environment variable wasn't being copied into call
	packets.  Read and write to audio devices in the proper fragment
	size remembering to keep UDP packets smallish.	Enhance stats
	command to display all sorts of connection stafs.

2001-12-16 16:11  shane

	* protocol.h: Added pkt_connstats packet type.

2001-12-16 15:25  shane

	console.h, intercom.c, intercom.h, iobuff.c, iobuff.h,
	pkthandler.c, pkthandler.h, protocol.h: Pretty much a complete
	rewrite.  Not sure if anything is the same.  Drop the idea of
	client / server and use a peer to peer model.  Added a
	command-interface optionally using readline and command history. 
	Extended the protocol to support a call based process.	Some other
	protocol extentions.  Send audio data over a UDP connection while
	using TCP for control.	Use a buffered i/o scheme for anything
	which can block so as to be as asynchronous as possible.

2001-12-13 15:40  shane

	* autogen.sh: We don't need the LGPL yet if at all.

2001-12-13 15:34  shane

	statistics missprint.

2001-07-10 19:40  shane

	* Makefile, common.c, common.h, intercom.c, intercomd.c: Split
	client and server parts into two seperate programs (intercome and
	intercomd).

	Handle short reads on sockets properly 2001-06-29: SW Listener now
	exits cleanly on terminating signals * Added packet headers to all
	outgoing frames * Drop packets if we get backlogged too far
