Most of the commands will return a simple string status. Exceptions are the stats commands, which return an alist, and the reserve command, which returns a pair (job-id . data) if a job is reserved.
All hen commands also accept keyword arguments #:tcp-in and #:tcp-out to override hen-in and hen-out, which are the default ports, initially unspecified.
