04/15/94        v3.7d    1)     Made transition from voice to command mode for
                                the Zoom modem more reliable.  This should fix
                                the problem with failing to recycle after calls.
                         2)     Revised method of playing numbers.  The NUMS.BIN
                                file has been replaced with NUMS0.BIN and
                                NUMS10.BIN.  These are REQUIRED files for proper
                                operation.  The OVER59.BIN has been replaced
                                with OVER99.BIN.
                         3)     Fixed problem overrunning ZOOM modem's voice
                                buffer when playing long ( > 10 secs) messages.

03/12/94        v3.7c    1)     Tested and revised support for the Zoom modems
                                on an actual Zoom modem.  Pre-recorded voice
                                files are now available for the Zoom.

02/19/94        v3.7b    1)     The ZyXEL modem will enter an indeterminate
                                mode the first time that at AT+FCLASS=8 is
                                sent to the modem after going off hook with
                                ATH1.  The modem must be placed back on hook
                                by lowering DTR.  The workaround implemented
                                is to send ATH0#B1+FCLASS=6 after a ring but
                                before ATH1.  Then send AT#B1+FCLASS=8.  This
                                has solved the problem at least for my site.
                         2)     If you get the "Sorry, your evaluation period
                                has expired" message, then you may not have
                                followed the instructions in the README! file.
                                Please install ANSWER.EXE in a newly created
                                directory.  Also, ANSWER.EXE shareware version
                                will not run from a root directory.

02/09/94        v3.7a    1)     Added support for the Zoom modem.  The support
                                is actually still in beta testing since I do
                                not have a Zoom modem on hand.  However, the
                                commands have been implemented and "should"
                                work.  I do not have pre-recorded voice files
                                for this modem, nor do I know whether or not
                                the compression standard is compatible with
                                the ZyXEL's or the SoundBlaster's ADPCM format.
                         2)     Updated address information for new location.
                         3)     Added support for "Line Select" during play
                                and recording operations.  The default command
                                strings have changed.  To allow the new line
                                selections to work, you should delete your
                                OPTIONS.DAT file and reenter your options.

Cygnus Data Systems is moving to Seattle, WA and will have a new address
as of 11/01/93.  The new address is unknown at this time, but will be
announced in the next release of Answer.

10/11/93        v3.6i           Added voc<=>zyx conversion routine.

07/17/93        v3.6h           Repaired error in initialization codes for
                                record and play being swapped.  This resulted
                                in both record and play operations being
                                as soon as they started.

07/08/93        v3.6g           Fixed result code identification failure in
                                the ZyXEL initialization routine.  If you've
                                tried previous versions, you may need to delete
                                your OPTIONS.DAT file prior to running this
                                version.

07/08/93        v3.6f           Fixed critical failure to set the comm port
                                baud rate upon first time initialization.
