TITLE:  SET CHARACTER ATTRIBUTE ON WY-60 WITH IBM3161 PERSONALITY

DATE:   10/28/92

PRODUCT:  WY60

THE ISSUE:
        WY60's IBM 3161 Set Character Attributes don't work as IBM

RESOLUTION:
        There has been reported a problem with using certain Set
        Character Attributes command in IBM3161 personality. The
        following describes the proper SET ATTRIBUTE command with
        options:

        Esc 4 <Pa1> where Pa1 is a variable having different functions
                    depending on which bit is set:

        Pa1  Bit 7: Always 1
                 6: Always 0
                 5: Non-Display (Blank)
                 4: High Intensity
                 3: Blink
                 2: Underline
                 1: Reverse

        e.g. To set Non-Display and Reverse is Pa1 = 01010001 = 51(hex)
        which is the character Q. The problem with the WY-60 is that
        turning on bit 5 of Pa1 has no effect on the screen output.



        A work-around was found, however. If you turn on bit 6, the
        correct attributes are displayed including Non-Display (Blank)!
        The code that the terminal recognizes from the above example
        would then become 01110001 = 71(hex) = the character q.

        The following is a list of all Set Character Attribute
        possibilities:

        Command  Non-Disp HexVal/Pa1   Description
        ----------------------------------------------------------------
        Esc 4 a   (q)       61         Reverse Video
        Esc 4 b   (r)       62         Underline
        Esc 4 c   (s)       63         Reverse/Underline
        Esc 4 d   (t)       64         Blink
        Esc 4 e   (u)       65         Blink/Reverse
        Esc 4 f   (v)       66         Blink/Underline
        Esc 4 g   (w)       67         Blink/Underline/Reverse
