talk — talk to another

talk is a two-way, screen-oriented communication.

Once communication is established, the two parties can type
simultaneously, in separate regions.

Permission to be a recipient of a talk can be denied or granted.

The talk shall fail when the user lacks appropriate privileges to perform the requested action.

When exchange cannot be supported,
report an error describing the deficiency.

The following environment variables shall affect the talk:

interpretation of text
arguments and input

the results are undefined.

The talk was considered to be a “better” communications interface.

All references to networking abilities were removed as being outside the scope of this volume

Historical talk terminate the conversations
when either user breaks out of the session.

This can lead to adverse consequences.

* Neither party can be required to communicate
