Running OSI applications over TCP/IP (RFC1006) is automatically
    enabled when you install and configure DECnet.  To enable DECnet
    over TCP/IP (RFC1859), you can either run "decnetsetup advanced"
    and answer "yes" to the question "Do you want to configure DECnet
    over TCP/IP?" or you can run dxdecnetsetup, select the advanced
    format, and select the "Configure DECnet over TCP/IP" option.
