Version 1.6 of the Sim390 mainframe emulator has support for tn5250 telnet clients. Sim390 acts as a tn5250 server, which allows a tn5250 client to log in to the MUSIC/SP operating system. Sim390 translates between 5250 and 3270 terminal data streams, so that MUSIC/SP thinks it is talking to a 3270, while the tn5250 client thinks it is talking to a 5250 server such as an IBM AS/400 or iSeries midrange computer. This is useful for testing tn5250 clients. Sim390 has been tested successfully with several tn5250 clients. Not all features of 5250 terminals are supported.
