If user_a wants to talk to user_b and both are logged on, he/she may want to use the talk command:
talk user_b[node]
When talk is invoked, the screen of the originator is split into two equal parts (a horizontal line of hyphens separates the two parts). user_b receives a request to answer:
Message from Talk_Daemon
talk: connection requested by cantin
talk: respond with: talk cantin
Once user_b, in this case cantinneon, responds to
cantinnickel, his
screen will be split in two: the top portion of the screen always displays
the local user's messages, and the bottom portion the
remote user's message.
Characters are displayed as they are typed.
To close the connection, press <CTL-C>.
