Well...sort of. It's also used to interrupt applications in progress, especially TSO, and in some session managers (Legent's TPX springs to mind) to signal a desire to switch from the current session to the manager screen. As such, it is a useful (possibly, in some environments, necessary) thing to implement. I know that there's a canonical implementation, since FTP Software's tn3270 client does it in a manner that our Interlink telnet server understands; I just don't know what it is. -- Jay Maynard, EMT-P, K5ZC, PP-ASEL | Never ascribe to malice that which can jmaynard@thesis1.hsch.utexas.edu | adequately be explained by stupidity.
