The term "5250" now refers to the content of the data stream itself; few physical 5250 terminals still exist, although they are still used to provide a "connection of last resort," hard-wired to the host computer. Robustly constructed, 5250 terminals weighed roughly 36kg (80 lbs.) The 5250 terminals generated an audible clicking sound as the user typed, similar to the electric typewriters of the era. Today, it is more common to use PC or web-based terminal emulation packages that can interpret and display 5250 data streams. Commonly used emulators are IBM's own iSeries Access,TN5250, an open source project, WRQ's Reflection, SDI's TN3270 Plus, Cybele Software's z/Scope Express 5250 and Hummingbird's Host Explorer.
A number of modern 5250 emulaton packages include additional features beyond displaying the data stream; for example, IBM's iSeries Access includes support for graphical system administration, remote system console connectivity, file transfers, macros, printer emulation, and support for client-server database connectivity.Examples of these would include Psion's Teklogix radio data terminal or its counterpart, LXE terminals.
