Package ID


an IBM 3270 terminal emulator for Windows.


x3270 is an IBM 3270 terminal emulator for the X Window System and Windows. It runs on most Unix-like operating systems – e.g., Linux, Mac OS X, Solaris and Cygwin. It also runs natively on Windows.

x3270 runs over a TELNET connection, emulating either an IBM 3279 (color) or 3278 (monochrome). It supports:

  • The full TN3270E protocol
  • SSL/TLS (via the OpenSSL library) for encrypted sessions
  • APL2 characters
  • Non-English character sets, including Russian, Turkish, Hebrew and DBCS Chinese and Japanese
  • IND$FILE file transfer
  • NVT mode (emulating a color xterm)
  • A pop-up keypad for 3270-specific keys
  • A scrollbar
  • Printer session integration
  • Extensive debugging and scripting facilities

It does not yet support graphics. x3270 is distributed as source code, and can be used for free.

x3270 is available in several different forms:

  • x3270 is for use on an X graphics display
  • c3270 is a curses-based version for use on a dumb terminal (e.g., a serial terminal or a Linux console)
  • wc3270 is the Windows console version of c3270
  • s3270 is a displayless version for writing screen-scraping scripts
  • ws3270 is the native Windows version of s3270
  • tcl3270 is similar to s3270, but integrated with Tcl
  • pr3287 is for printer emulation
  • wpr3287 is the native Windows version of pr3287

Also available is x026, an IBM 026 Keypunch emulator.
