/TIMEOUT=OpenVMS_delta_time

    Optional. Default: ::01 (1 second).

    Minimum timeout period for initial remote procedure call (RPC)
    request retransmissions.

    Specify the timeout period as your estimate of the typical round-
    trip time for RPC requests. For slower-speed links - for example,
    NFS traffic over SLIP - specify a value that is larger than the
    default.

    Example: For a maximum read/write size of 8192 (see the /DATA
    qualifier) over a 19,200-baud SLIP line, set the absolute minimum
    timeout value as follows:

    10240 bytes*8 bits per byte
    --------------------------- = 4.27 seconds
       19,200 bits per second

    Here, the 10240 bytes is 8192 data bytes plus the worst-case RPC
    overhead. Because 4.27 seconds is the absolute minimum, a more
    realistic value for this link is 15 to 30 seconds to allow for
    other traffic.
