SYSMANHELP.HLB  —  Sys Parameters, 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.
