It's an adaptation of the 5250 protocol used to connect display stations (i.e. intellectually challenged terminals) to AS/400 via twinax. Are you trying to connect to another PC that has a 5250 emulator in it via twinax? (Hope not ... don't think this would be easy). If you're trying to connect to AS/400 just start TCP/IP and the telnet server on the 400 and connect that way. AS/400 telnet prefers to use tn5250, but it'll also talk tn3270 and then VT220 and VT100. > Is there source to a tn5250 program available somewhere? I don't know of any tn5250 source code that's available to the public. If you want more info on tn5250 there is an RFC for it: http://ds.internic.net/rfc/rfc1205.txt You might also get more information at the News/400 magazine web site: http://www.news400.com. In particular they have a white paper posted at their site with the title "The Evolution of TELNET 5250 (TN5250)", http://www.news400.com/education/WhitePapers/Telnet/Index.html It sounds interesting and I keep meaning to actually read it some day ... :-) Other AS/400 web sites are: http://www.as400.ibm.com and http://www.midrangecomputing.com/ Hope this helps, -john martz ------------116F59AD11EE0 Content-Transfer-Encoding: 7bit Content-Type: text/html; charset=us-ascii <HTML><BODY> <DT>Joe McGuckin wrote:<BR> > <BR> > Does anyone know how a tn5250 session differs from a regular telnet<BR> > session?
