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. +
