TOPIC:  ARROW KEYS DIFFERENCES BETWEEN WY85 AND WY185 TERMINALS

DATE:   10/06/92

PRODUCT:           WY-85 WY-185

THE ISSUE:
        Arrow keys are not compatible.

OVERVIEW:
        There is a functional difference between the arrow keys on
        the WY-85 terminal and the WY-185 terminals. The differences
        are detailed as follows:

        Arrow Key               WY-85    WY-185
        ---------------------------------------
        <Up Arrow>  Book Says   Esc[A    Esc[A
                    Actual Code EscA     Esc[A

        <Dn Arrow>  Book Says   Esc[B    Esc[B
                    Actual Code EscB     Esc[B

        <Rt Arrow>  Book Says   Esc[C    Esc[C
                    Actual Code EscC     Esc[C

        <LftArrow>  Book Says   Esc[D    Esc[D
                    Actual Code EscD     Esc[D
        ---------------------------------------

        Notice that the WY-185 terminal produces the CORRECT code. The
        WY-85 omits the "[" . Differences include all personalities,
        except VT-52, and it doesn't matter whether you have 7 or 8
        bits selected.

RESOLUTION:
        The solution for this problem will have to be a software
        solution, since the WY-185 terminal does the codes correctly,
        there will not be a hardware fix for this. One solution for
        UNIX/XENIX systems would be to change the termcap definitions
        to reflect the correct codes. Applications which are written
        for the WY-85 terminals will require modifications to the
        applications to work correctly.
