Welcome to
This Wiki contains documentation for the x3270 family of IBM 3270 terminal emulators.

Interactive emulators

 * x3270 is the original version. It is a graphical interactive 3270 emulator that runs on Linux, Solaris, MacOS (with XQuartz installed), FreeBSD and other Unix-like operating systems.
 * wx3270 is a modern interactive graphical 3270 emulator for Microsoft Windows.
 * c3270 is an interactive 3270 emulator that runs on a Unix character-mode terminal. A character-mode terminal can be an emulator such as xterm, gnome-terminal, kterm, a MacOS Terminal window, or a Linux console, or a real hardware terminal such as a DEC VT100.
 * wc3270 is an interactive 3270 emulator that runs in a console window on Microsoft Windows.

Screen scraping tools

 * s3270 is screen-scraping tool. (On Windows, it is also called ws3270.)
 * tcl3270 is a wrapper around s3270 that facilitates writing Tcl scripts for screen scraping.

Daemon processes

 * pr3287 is an IBM 3287 printer emulator. It can be used in conjunction with one of the interactive terminal emulators to associate a printer with the login session, or it can run standalone to direct mainframe print jobs to a printer on a workstation. (On Windows, it is also called wpr3287.)
 * b3270 is a generic back end for 3270 emulators. b3270 implements the 3270 protocol and host input/output, and communicates with a front end application using a simple XML-based protocol..

A note on terminology
Throughout this wiki, the term x3270 is used in two ways. With a hyperlink, it refers specifically to the x3270 3270 emulator. Without a hyperlink, it refers to all of the members of the x3270 emulator family. This is done when squeezing the phrase "all of the members of the x3270 emulator family" into to text would make it awkward to read.

A note on versions
This wiki describes x3270 release 4.0 and wx3270 release 1.0. Much of the information pertains to earlier versions, but fair amount of it does not.
