37 .Nd remote user communication server
43 is the server that notifies a user that someone else wants to
44 initiate a conversation.
45 It acts as a repository of invitations, responding to requests
46 by clients wishing to rendezvous to hold a conversation.
48 In normal operation, a client, the caller,
49 initiates a rendezvous by sending a
56 .Aq Pa 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).
62 the caller then sends an
64 message causing the server to
65 broadcast an announcement on the callee's login ports requesting contact.
67 When the callee responds, the local server uses the
68 recorded invitation to respond with the appropriate rendezvous
69 address and the caller and callee client programs establish a
70 stream connection through which the conversation takes place.

78 option turns on debugging logging.
82 option turns on accounting logging for

102 in a machine and byte-order dependent fashion.
103 When this was corrected, it required a protocol
104 change, which necessitated a different daemon to
110 The old daemon has long since been removed,
111 but the detritus remain.
