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.
