Library /sys$common/syshlp/nclhelp.hlb set, routing, circuit, explicit_receive_verification  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Support: All
    Default: True          Value: True or false

    Type of password verification performed at circuit
    initialization. If true, the received verifier is checked
    against the value of the characteristic receive verifier for
    this circuit, if any. If false, the received verifier is checked
    against the set of verifiers specified in the routing permitted
    neighbor entities. This attribute is supported only if the
    characteristic type is set to ddcmp, hdlc, x25 static incoming,
    x25 static outgoing, and x25 permanent.
