IX. Supporting Tools

*1. talk: The form of the command is talk userid@host.domain .  
This command lets you connect your computer to someone else's (on the internet)
and type messages back and forth.
* You see what the other person types as the keys are pressed.
* You can talk locally or long distance via the internet
* Both your screen and your recipient's are split so you can see both parts of 
the 'conversation'.  Also both parties can simultaneously type in their screen 
portions.
* When talk is invoked, the talk daemon checks for the user being logged in and
then sends a request for a connection every 10 seconds.  You may give up by 
typing <Ctrl-C>.
* If you receive a talk request, enter the command as written exactly.
* When "talking", if you make a mistake, you can backspace, but more efficient 
is to type <Ctrl-W> and <Ctrl-U> to delete a full word or the current line.
* Either person can terminate the conversation by typing <Ctrl-C>. However, 
you should say goodbye in print and await acknowledgement before exiting.
* talk is informal. It's okay to express all of your misspellings without 
shame.
* refuse to talk by typing on your UNIX command line mesg n (mesg y permits 
messages to be sent to your terminal)
