is a
visual communication program which copies lines from your terminal to that
of another user. Options available: If you wish to talk to someone on
your own machine, then is just the person’s login name. If you wish to
talk to a user on another host, then is of the form If you wish to talk
to a user who is logged in more than once, the argument may be used to
indicate the appropriate terminal name, where is of the form or When
first called, contacts the talk daemon on the other user’s machine, which
sends the message Message from TalkDaemon@his_machine... talk: connection
requested by your_name@your_machine. talk: respond with: talk your_name@your_machine
to that user. At this point, he then replies by typing 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;
their output will appear in separate windows. Typing control-L (^L) will
cause the screen to be reprinted. The erase, kill line, and word erase characters
(normally ^H, ^U, and ^W respectively) will behave normally. To exit, just
type the interrupt character (normally ^C); then moves the cursor to the
bottom of the screen and restores the terminal to its previous state. As
of netkit-ntalk 0.15 supports scrollback; use esc-p and esc-n to scroll your
window, and ctrl-p and ctrl-n to scroll the other window. These keys are now
opposite from the way they were in 0.16; while this will probably be confusing
at first, the rationale is that the key combinations with escape are harder
to type and should therefore be used to scroll one’s own screen, since one
needs to do that much less often. If you do not want to receive talk requests,
you may block them using the command. By default, talk requests are normally
not blocked. Certain commands, in particular and may block messages temporarily
in order to prevent messy output.

The protocol used to communicate
with the talk daemon is braindead. Also, the version of released with
uses a different and even more braindead protocol that is completely incompatible.
Some vendor Unixes (particularly those from Sun) have been found to use
this old protocol. Old versions of may have trouble running on machines
with more than one IP address, such as machines with dynamic SLIP or PPP
connections. This problem is fixed as of netkit-ntalk 0.11, but may affect
people you are trying to communicate with.
