Yes, it can be used. You will need an Internet provider, and you will
likely need an IP package for the OpenVMS system -- DEC TCP/IP Services
(UCX) is one such package -- and you will need a provider-specified
point-to-point data link running a provider-specified protocol, and you
will need a package on the OpenVMS system that supports the provider-
specified protocol if UCX does not support the protocol and data link.
