[Boost-users] [asio] Howto bind *client* to a specific port?

A NewbieQ: From a client app I want to connect to a server app on a remote host (say port 6666). A requirement is that the client shall be bound to a defined port (say port 5555). How to do this in asio? Does the client need to use an acceptor? (ok, this maybe sounds non-sensical, but who knows... :-)
