    ForceC1Controls Property
    In This Topic
    Gets or sets whether Reflection interprets characters from certain host character sets as control codes.
    expression.ForceC1Controls As Boolean
    where expression is a variable that represents a Terminal Object
    This property applies only when emulating a VT or ANSI terminal (that is, it does not apply to Tektronix emulation).

    Certain host character sets (such as PC-English or Chinese BIG-5) contain characters whose code values overlap those in the C1 control character region (characters 128 through159). This property determines whether Reflection interprets character codes in this overlapping region or displays them as host characters.

    When this property is set to true, Reflection interpret character codes between 128 and 159 as C1 control codes. This allows VAX applications like TPU to work properly; however, characters defined in this range are no longer displayable.

    When this property is set to false, Reflection interprets C1 character codes only for host character sets that support it (that is, host character sets that do not define displayable characters in the C1 control range).
