    EnquireAcknowledge Property
    In This Topic
    Gets or sets a value indicating whether InfoConnect uses a form of handshaking called Enquire Acknowledge (EnqAck).
    Property EnquireAcknowledge As Boolean
    Dim instance As ITerminal
    Dim value As Boolean
    instance.EnquireAcknowledge = value
    value = instance.EnquireAcknowledge
    bool EnquireAcknowledge {get; set;}

    Property Value

    The default value is false for UNIX and OpenVMS and ReGIS Graphics emulations.
    Host computers use Enquire Acknowledge handshaking to prevent the terminal from falling too far behind the host system and losing data.

    When the host system has a block of more than 80 characters to send, it sends 80 characters and an ASCII Enq character, and then stops transmitting. When InfoConnect has processed all of the characters preceding the Enquire, it sends an ASCII Acknowledge character, which tells the host that InfoConnect has caught up and is ready for more data.
