话带数据中传真解调程序

	0.9.8

	Fixed tone detection stuff! Dialtone, Busy and Answer tone detection works.
	(I have tested this with the -d option.)
	
	Removed all byte_59xxx variables replacing them with their S(0xYY)
	equivalent.

	Added some fixes from Pavel, in particular the use of Jamies'
	x_output which doesn't have my bugs in! Voice stuff should now work!
	
	Added loads of V8bis stuff, including DSP code. Just need to
	get it working!

	Added initialisation code for Japan. Added extra code in some
	io related (UART/AT) tasks.

      0.9.7
	
      Fixed some bugs in the dial tone detection code. Added more tone/ring
      detection code and some bodge routines for setting things up prior to
      tone detection. Ring detection works! Added -r option to wait for ring
      in and then go offhook. 

      I have tested ringing in with the -r option using a handset to dial the
      modem. The modem detects the call and goes offhook OK. I can hear myself
      talking on the modem's internal speaker. However the modem does not hang
      up properly, after the modem has gone on hook the call is still connected.
      The caller must then hang up to drop the connection.
	
      When dialling out the modem hangs up OK.

      Added extra commands for new and some existing functionality to the
      command mode (-c option). This is now documented (with examples) in the
      README file.

      0.9.6

      Added optional support for real interrupts, see README.INTERRUPTS.	
      Overhauled initialisation routines, mostly robbed from jamie. Fixed
      bugs in dp_downloap_dsp. Created new file dp_call.c to hold call related
      stuff. Fixed a few other minor bugs.

	I've done a major update of the code. I've added the voice stuff that
	Pavel and Jamie have done, though I don't have the hardware to test it
	thoroughly. I have moved a lot of code around to try to make things
	easier in the future. In particular:

	HAL.c and HAL.h have been removed.

	pci_utils.c and pci_utils.h now contain the PCI specific code
	taken from ltmodem.c that finds the modem etc.

	portIO.c now has some code moved from ltmodem.c which is used for
	direct monitoring and writing to ports. All the former HAL calls
	have been replaced with the "pausing" versions of the port I/O
	calls (inb_p, outb_p, etc.). 

	dsp.c and voice.c have been added from Pavel's stuff with some minor
	changes.

	data.c and data.h have the data transfer specific stuff in.

	The aim of this build is to incorporate as much of Pavel's and Jamie's
	code as possible whilst having a structure of lots of smaller files.
	Thus making making modifications easier to make and track.
