This very much depends on your TFTP server.  Most are restricted
to a particular directory [tree] for security reasons, so you aren't
allowed to use a whole path name.  For example, on Red Hat (Fedora)
systems, TFTP can only serve from the /tftpboot directory and that
is implied in the path name, so the RedBoot command:
  RedBoot> lo dir/file.test
would come from /tftpboot/dir/file.test

You'll need to check the documentation on your TFTP server setup
for the exact details.
