easy...

talk person
or
talk ttyname

person - If you wish to talk to someone on your own machine, then person is just the person's login name. If you wish to talk to a user on another host, then person is of the form `user@host'.

ttyname - If you wish to talk to a user who is logged in more than once, the ttyname argument may be used to indicate the appropriate terminal name, where ttyname is of the form `ttyXX' or `pts/X'.
