talkd(8c)
Name
talkd − inter-terminal communications server
Syntax
/etc/talkd
Description
The talkd program is the server for the talk(1) program. The server provides a rendezvous method for the requesting (possibly remote) talk and the local responding talk.
The talkd server is invoked by inetd() when it receives a packet on the port indicated in the talk service specification.
Restrictions
The talkd server does not strictly follow network byte order in its packet format and may have difficulty in talking with implementations of talkd on other architectures that do not take this into account.
The version of talk released with ULTRIX V3.0 uses a protocol that is incompatible with the protocol used in earlier versions. Starting with ULTRIX V3.0, the talk program communicates with other machines running ULTRIX, V3.0 (and later), and machines running 4.3 BSD or versions of UNIX based on 4.3 BSD.
The talk command is not 8-bit clean. Typing in DEC Multinational Characters (DECMCS) causes the characters to echo as a sequence of a carets (^) followed by the character represented with its high bit cleared. This limitation makes talk unusable if you want to communicate using a language which has DECMCS characters in its alphabet.
