SCSFLOWCUSH

   Specifies the lower limit for receive buffers at which point
   system communication services (SCS) starts to notify the remote
   SCS of new receive buffers. For each connection, SCS tracks the
   number of receive buffers available. SCS communicates this number
   to the SCS at the remote end of the connection. However, SCS does
   not need to do this for each new receive buffer added. Instead,
   SCS notifies the remote SCS of new receive buffers if the number
   of receive buffers falls as low as the SCSFLOWCUSH value.

   The default value is adequate on most systems. If a systems
   communication architecture (SCA) port is not configured on your
   system, this parameter is ignored.

   SCSFLOWCUSH is a DYNAMIC parameter.
