What terminal emulation does putty support? I looked on a couple of web sites -- including
http://www.unixwiz.net/techtips/putty-openssh.html -- and could not find reference for setting emulation type.
On putty's org page, it says it is for Windows, not Linux, so I am not quite sure who maintains the Linux version putty or if putty's .org page is incorrrect,
http://www.putty.org/.
My primary desktop is Kubuntu. I needed an emulator that would allow multiple Unix/Linux host emulation, including specialized mapping of keys. The only product, open source or not, that I could find was PowerTerm Interconnect for Linux from Ericom software,
www.ericom.com. It appears PowerTerm Interconnect for Linux supports VT400 emulation.
I like open source, and try to use only open source products. Sometimes, you have to go with paid-for products.
