The IBM 3270 Terminal Applications suite consists of seven applications. x3270 is an IBM 3278/3279 Terminal Emulator for the X Window System. c3270 is a curses-based 3278/3279 emulator. wc3270 is the Windows console version of c3270. s3270 is a script-based screen-scraping application for IBM hosts. tcl3270 is a Tcl- or Extended Tcl-based IBM host screen-scraping language. pr3287 is an IBM 3287 printer emulator, which can be invoked from x3270 or c3270, or can run standalone as a daemon. wpr3287 is the Windows version of pr3287. x3270, c3270, wc3270, s3270 and tcl3270 can emulate a color (3279) or monochrome (3278) terminal. They implement the TN3270E protocol, support IND$FILE file transfer, printing via 3287 emulation, and multiple host character sets (including non-Latin sets and DBCS Chinese and Japanese).
pr3287 is an emulator for an IBM 3287 printer, running over a telnet session. It supports TN3270E and the older RFCs. It can be associated with an existing session, automatically invoked from x3270 or c3270, or it can run standalone as a daemon. It supports formatted and unformatted printing, and SCS.
