A 3270 terminal emulator for connecting to IBM mainframes.
Name: x3270
Homepage: http://x3270.bgp.nu/
Why: I couldn't find any other IBM 3270 terminal emulators in the Solus repositories.
Open Source: Yes. Under a standard BSD license.

The use case for this is when a university student taking an IBM System Z mainframes course, or when a system/business logic programmer for one of the top 100 banks in the world (or Walmart, or $MegaCorp) needs to access their company's mainframe, they don't want to have to switch to Mac or Windows or install a commercial proprietary piece of software to do it.
The only other option on Linux is Ericom TN3270, which is commercial software. And on Windows you've got SDI TN3270 Plus and Mochasoft TN3270, both of which are also commercial software.
If you're asking what the use case is for this software for the average person, there isn't one. All telnet 3270 terminal emulators are utterly useless to anyone who doesn't have an IBM System Z mainframe login.
If you're willing to become the maintainer of the package, I'll accept it for inclusion.
This has sat in accepted for inclusion for over 30 days. Clearly, there is a lack of demand for the inclusion of this software, nobody has stepped up to provide a completed patch, maintain it, and properly integrate it. Closing as a result. Feel free to reopen but only when someone offers a patch via our proper patch submission methods and volunteers to be maintainer.
