specifying protocol for service

[bouma@cs.purdue.edu]

When you call the function 'invoke-service-on-host' is there any way to
specify the protocol for it to use? When I run that function on a host that
is not in the namespace, I get thrown into the debugger. It does not know
that that host supports that service. However, the first option in the
debugger, s-A, asks to try the service anyway with some protocol the local
machine knows about. I would like to give it the protocol I want to use
and have it skip looking at the namespace. I should get into the debugger
only if it fails to get a connection. Please tell me how this can be done.
