PC-Talk is a communications software program. It was one of the first three widely popular software products sold via the marketing method that became known as shareware.

<chat> ("new talk") An update of the Unix "talk" program, old versions of "talk" being referred to as "old talk". New talk and old talk are generally incompatible, and attempts to get them to communicate result in entirely unhelpful error messages. On most modern Unix systems, the program "talk" is new talk, with some SunOS versions being a notable and annoying exception to this. (1997-09-11)

Version: V3.0 Patch Level 1. <networking, tool> A multi-user chat program by Britt Yenne <yenne@austin.eds.com>. YTalk works almost exactly like the standard Unix talk program and even communicates with the same talk daemon(s), but YTalk supports multiple connections. Multiple user names may be given as command-line arguments, in the form "name#tty@host" where the optional "#tty" specifies a particular tty. YTalk is able to communicate with both existing versions of Unix talk daemons. Once connected, typing escape gives access to a menu of commands to add or delete users, trace to a file, or set options. If run under the {X Window System}, YTalk will use separate X windows for each user in the conversaton, otherwise it will split the terminal screen between them. E-mail: <ytalk@austin.eds.com>.
