The man pages for all the machines that I use (Ultrix & sunOS) state that
you need to do something like:

	rcp mach.user:file localfile

Rcp is similar to cp, in that you need to specify at leas two names on the
command line.  When there are more than two, the last must be a directory.
Rcp also allows the -r flag, which does recursive copies.  (The last file
must be a directory.)  Some version of rcp have other flags, but they are
not universally supported.

Rcp uses the following as a filespec:

	[remotemach[.remoteuser]:][filename]

The filename is the name of a file specified on the appropriate machine.
It may be either the name of a file, or a directory, as appropriate.  It
need not exist, if the conext allows that.  (That is, the destination file
need not exits.

When remotemach (with the :) is not specified, the filename is taken to be
on the local machine.  When remoteuser is not specified, it defaults to the
name of the current user.  (Different implementations vary on whether real
uuid or su'ed uid is used when su'ed.)  If filename is nonexistent (only
valid for destination), . is assumed (that is, the login directory for
remoteuser.  Filename must be present if remotemach is absent.

That is, the following are valid:

	localfile
	remotemach:file
	remotemach.remoteuser:remotefile
	remotemach:		# only for destination
	remotemach.remoteuser:	# ditto

Hope this helps.
