8074/8075 Release 031127 changes from 001215/030328 are: - Changes to modem init to improve performance. --------------------------------------------------------------- 8075 Release 030328 changes from 010418 are: - 0-based row/col positioning. - Max. EIA-708 window size 12 rows tall. - text length checking to <= 32 columns. --------------------------------------------------------------- 8074/8075 Release 010418 changes from 001215 are: - Upstream XDS packets can now be removed entirely from the data stream, same as in 8084. See document 8084_Chg1.2-1.PDF for details. - Added "XDS Packet Pause" for better interop with some XDS decoders. - Improved processing of upstream XDS data interleaved with new XDS data being inserted. - DST flag indication on front panel. If DST is ON, separator character between hours and minutes will be a period (.) instead of a colon (:). - "Wincue filter" to filter-out bad data from Wincue teleprompters. - Caption Processor now filters-out more invalid upstream data. - Fixed a minor bug in upstream F2 data processing. --------------------------------------------------------------- 8074/8075 Release 001215 changes from 001117 are: * fixed bug that would unintentionally block all upstream captions in a field. This bug was introduced in R001117 release. - Improved interop with "808X ConfigWare" software package. --------------------------------------------------------------- 8074/8075 Release 001117 changes from 000721 or 000329 are: - Added "XDS Force Packet Insert" same as 8084. - Modified upstream caption processor to filter-out invalid characters in upstream F1 captions. --------------------------------------------------------------- 8074 Release 000721 changes from 000329 are: - Fixed a bug in the calculation of UTC time when given local time or calculation of local time when given UTC time using ^Ac command. --------------------------------------------------------------- 8074/8075 Release 000329 changes from 990715 or 990721 (8075) are: - Fixed 8075 bug that trashed XDS article transmission. - Fixed bug that trashed state of RTC DST flag and offest the time. - Fixed ^A? text to read "Model 8075" instead of "Model 8074" on 8075 only - "VIDEO MISSING" messages do not appear if bypass relay engaged. - Fixed ^A6 TX command to put XDS stream in NULL STATE. --------------------------------------------------------------- 8074 Release 990715 changes from 981218: - Lines of article text can now exceed 32 characters, allowing longer WebTV URL strings to be encoded into text channel 2. - New Port B functions added to allow serial commands input from one one serial/modem port to be echoed out of Port B. - New Port B functions added to allow outgoing CC data to be echoed out to Port B as well, or to allow CC data input to Port B to be encoded directly into outgoing video. --------------------------------------------------------------- 8074 Release 981218 changes from 980708: - Default modem baud rate changed to 2400 to provide faster (more reliable) modem negotiations - Better Uart/Modem initialization error detection. - Added routines to alter only the necessary registers of the decoder to prevent slow decoder initialization from causing lost upstream captions. - added routine to check validity of work in progress, and reset modem stack if necessary to prevent permanent keyboard lockouts. - increased 1st power-up stabilization delay to 250ms to allow NV Ram controller to start up and enable XRAM access. This was preventing the XRAM from being properly cleared on fast-boot power-ups, and causing false RAM BUFR BAD messages - Changed sense of HW_VALx so that it could be used to signal where the UART/MODEM initialization had failed. - Added litod_set_ln() call to ^AE default handler, since o/p line number was being changed but decoder was not being changed. - Added CR LF to modem training string to clear out any potential leading garbage. - FX87D4 changes were LCA design patches which moved the PAL CC waveform closer to 'nominal' 10.5 uS. Analog output timing was changed to more accurately reflect digital timing.
