Application CANCEL

One of the parameters on the Open(PLU) OK Response, which the application sends to the local node, specifies whether the application generates CANCEL (or EC) to terminate an inbound chain that has received a negative response. If this option is not selected, the local node generates a CANCEL request when it receives a negative response from the host to an incomplete chain.
