- 06.05.23 - 0.0.3 - Steve Underwood <steveu@coppice.org>
- - T.38 now implemented, though it needs further polishing.
- - G.726 and G.722 now implemented.
- 04.08.29 - 0.0.2 - Steve Underwood <steveu@coppice.org>
- - T.4 no longer uses libtiff for compresion and decompression on the line side
- (it is still used to handle the TIFF files). Spandsp no longer depends on
- accessing the "internals" of libtiff. New 1D and 2D compression and
- decompression code now handles the line side. This should be more robust than
- using libtiff, and handles the fudging of bad scan lines rather better.
- - T.30 line turn-around timing corrected.
- - T.30 DCS header contents corrected.
- - T.30 provision for V.17 added, as an option.
- - T.30 now has a statistics interface, for applications to find details about
- image transfers.
- - T.30 processing now correctly closes TIFF files are they have been sent.
- - FAX header line insertion is now supported for transmitted FAXes.
- - asynchronous serial processing now has a V.14 compatible rate adaption option.
- - V.8 modem negotiation module added.
- - OKI ADPCM now supports Dialogic compatible operation at 6k samples/second, as
- well as 8k samples/second, using its own sample rate converter.
- - message queuing added to ease things like T.31 handling
- - incomplete skeleton (still rather nasty, to be honest) T.31 processing.
- - incomplete skeleton of V.22bis added. There is probably quite a bit to do
- to get this complete and robust. It probably requires the T.31 processing
- be expanded to something more like V.250, so it doesn't just handle FAX.
- - Incomplete V.17 added (there could be an IBM patent related to the TCM part of
- V.17, but I think it has expired. Don't distribute binaries of spandsp built
- with V.17 enabled until this is resolved - and the modem is completed, of
- course :-) ). The current version transmits OK. It receives OK with the
- long training sequence, but the symbol and carrier syncing isn't good enough
- for robust receiving with the short training sequence.
- - A basic BER tester has been added.
- - The faster modems now have proper shutdown procedures, whether one is defined in
- the spec. or not.
- - The modems (except simple FSK) now have APIs to access performance information.
- - A common GUI (using FLTK) added for the modem tests.
- - A bit more documentation added.
- - Some API inconsistencies cleaned up.
- - The usual bundle of assorted buglet fixes and polishing.
- 04.04.29 - 0.0.1k - Steve Underwood <steveu@coppice.org>
- - The first version which gives solid faxing for a large number of people.
