;; These examples are currently sbcl specific, but should be easily ported to
;; work with trivial-sockets, acl-compat or something similar.
;; They should be enough to get you started.
;;
;; eg. listen on port 6667 for incoming messages
;;
;; (osc-receive-test 6667)
;;
;; send a test message to localhost port 6668
;;
;; (osc-send-test #(127 0 0 1) 6668)
;;
;; listen on port 6667 and send to 10.0.89:6668
;; (note the ip# is formatted as a vector)
;;
;; (osc-reflector-test 6667 #(10 0 0 89) 6668)
