; though couldn't get them when ANSI.SYS isn't loaded. Now
; check if ANSI loaded before trying to display the settings.
; AC002 - P3331: ES was getting zeroed, which caused problems later in MODECP.
; AC003 - P3541: The retry status routine was assuming different format than
; the retry type byte was in. I fixed the status checking
; routine.
; AX004 - P3982: The screen was being cleared after the "Unable to shift

; AC005 - P4934: The multiplex number for ANSI.SYS was changed due to a
