53 /** \brief Interactive console server
55 This class provides an interactive console TCP server.
57 \todo Add readline support
58 \todo Add interactivity detection using timeout
59 \idea To support blocking commands, we could give the Client 'suspend()' and 'resume()'
60 members. suspend() would probably throw some kind of exception to transfer control back
61 to the Client instance. on resume(), the command would be called again, maybe setting
62 some flag or something. Example for use: Host name resolution: Here we can just built
63 our own little host-name cache. When the name is not found, we ask the resolver to
64 resolve it and call 'resume' when the name is found. Since it is in the cache now, the
65 command will now complete.
67 \implementation We do \e not provide an \c instance() member so we can easily later extend
68 the server to allow registering more than one instance, e.g. with each instance on a
69 differently firewalled port and with different security restrictions.
