41 .Nd remote user communication server
46 is the server that notifies a user that someone else wants to
47 initiate a conversation.
48 It acts as a repository of invitations, responding to requests
49 by clients wishing to rendezvous to hold a conversation.
50 In normal operation, a client, the caller,
51 initiates a rendezvous by sending a
57 .In protocols/talkd.h ) .
58 This causes the server to search its invitation
59 tables to check if an invitation currently exists for the caller
60 (to speak to the callee specified in the message).
63 the caller then sends an
65 message causing the server to
66 broadcast an announcement on the callee's login ports requesting contact.
68 When the callee responds, the local server uses the
69 recorded invitation to respond with the appropriate rendezvous
70 address and the caller and callee client programs establish a
71 stream connection through which the conversation takes place.
