Receive-Pacing Protocol

Receive-pacing protocol gives the PLU control over the number and the frequency of messages sent from the SLU on an LU-LU session. When the SLU receives pacing values in the BIND command, Personal Communications automatically enforces pacing for each SLU that communicates with the host.

During a positive response to a negotiable BIND command, you can change the pacing values to any number except 0. When the SLU sends the first message of a sequence, Personal Communications set a bit in the request/response header (RH) that indicates a pacing response is to be returned. If the pacing count is exhausted before either program receives a pacing response from the PLU, neither program can send additional data messages. If the application program issues a write operation and no pacing response is received, Personal Communications defer the write operation.
