[erlang-questions] how does an erlang Socket/Port look from inside?

[Dror Mein]

Hey all,

I want to eunit+meck test a simple telnet client which uses the guard is_port(Port).
how can I pass something in meck:expect/4 that will pass the guard?

is it a record/reference that I can make up?
can I use hd(erlang:ports()) -> #Port<0.0> without blowing up?
Thanks
