X5250

x5250 is a 5250 emulator written primarily by James Rich which uses the X11 Window System and lib5250 from the tn5250 project.

x5250 includes the following features:

• enhanced 5250 protocol support via lib5250
• simple copy and paste which can automatically align blocks of text

x5250 runs on several platforms including Linux, Solaris, FreeBSD, and even Linux on an iSeries LPAR. x5250 should compile and run on any platform that has a C compiler and supports X11.
