InfoConnect for Unisys
EnquireAcknowledge Property


Gets or sets a value indicating whether InfoConnect uses a form of handshaking called Enquire Acknowledge (EnqAck).
Syntax
'Declaration
 
Property EnquireAcknowledge As Boolean
'Usage
 
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.
Remarks
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.
