Library /sys$common/syshlp/latcp$help.hlb SET, NODE, Qualifiers, /RETRANSMIT_LIMIT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /RETRANSMIT_LIMIT[=count]

    Specifies the number of times your local node repeats
    transmission of a message to a service node after a transmission
    fails. If the transmission is still unsuccessful after these
    attempts, the virtual circuit between your local node and the
    service node terminates, along with all sessions associated with
    the virtual circuit.

    Use this qualifier only if your node allows outgoing connections
    (/CONNECTIONS=OUTGOING_ONLY or /CONNECTIONS=BOTH).

    Specify a value in the range of 4 to 120. The default is 8. The
    value you choose depends on the type of physical link used for
    your network, as well as the amount of traffic on the network.
    See your network manager for a suggested value. You cannot change
    this value if active or pending connections exist.
