Bug Fixes

BugFix Description Fixed
since
FIXWP
Jan 00
WP command does not work with ERTS versions that support the new SERIALPORT command (V3.29 and V3.30). more V3.30b
FIXSCASE
Jan 00
When using Staircases, the result table lists one constant value for each staircase instead of listing the staircase history. The constant value reflects the last setting of the staircase. more V3.30b
FIXEXKEY
Sep 98
ERTS versions earlier than 3.18 sometimes produce the error message
"EXKEY not connected" although EXKEY is present. The problem is
a wrong port timing on machines with fast CPU or CPU cache. more
V3.19
FIXVESA
Jan 97
Early ERTSVIPL versions do not recognize VESA VBE V2.0 which was not released at the time ERTSVIPL was shipped. V2.0 is not accepted because ERTS thinks it is V1.0. more V3.22
FIXMIDI
Jan 97
ERTS does calculate the frequency of absolute midi notes (octave = 0) in a wrong way more V3.22
