If you wish to talk to a user on another host, then \fIperson\fP is of the form \fIuser@host\fP. .PP If you want to talk to a user who is logged in more than once, the \fIttyname\fP argument may be used to indicate the appropriate terminal name, where \fIttyname\fP is of the form ``ttyXX''. .PP When first called, \fItalk\fP sends the message .PP Message from TalkDaemon@his_machine... talk: connection requested by your_name@your_machine. talk: respond with: talk your_name@your_machine .PP to the user you wish to talk to. At this point, the recipient of the message should reply by typing .PP talk \ your_name@your_machine .PP It doesn't matter from which machine the recipient replies, as long as his login-name is the same. Once communication is established, the two parties may type simultaneously, with their output appearing in separate windows. Typing control L (^L) will cause the screen to be reprinted, while your erase, kill, and word kill characters will behave normally. To exit, just type your interrupt character; \fItalk\fP then moves the cursor to the bottom of the screen and restores the terminal to its previous state. .PP Permission to talk may be denied or granted by use of the \fImesg\fP command. At the outset talking is allowed. Certain commands, in particular \fInroff\fP and \fIpr\fP, disallow messages in order to prevent messy output. .PP .SH FILES /etc/hosts to find the recipient's machine .br /var/run/utmp to find the recipient's tty .SH "SEE ALSO" mail(1), mesg(1), who(1), write(1) .SH BUGS The version of \fItalk\fP(1) released with 4.3BSD uses a protocol that is incompatible with the protocol used in the version released with 4.2BSD.
