pronounced open DOT term
Am open source emulator supporting 3270 and potentially later 5250 terminal types. The name, is derived from Ascert's package root for open source contributions. This being a terminal emulator, it's packages naturally have a .term suffix - hence the full name of "open.term"
The original purpose of this package was for code control of a host terminal. Over time if has become a useful, if basic, terminal emulator in it's own right.
The simplest way is direct from gradle:
gradlew execute
There are various properties you can use for a more enhanced experience e.g. the following will pre-populate the list of available hosts, skipping the initial dialog box:
gradlew -Dcom.ascert.open.term.available=127.0.0.1,2023,false,IBM-3278-2-E;10.1.2.3,23,false,IBM-32792-E execute
The original code was based on Freehost3270, and also the IETF OHIO API spec. Both of these being rather old and unmaintained, a lot has changed though hence the new naming and packaging. Licensing is based on LGPL to respect the original works.
An original org.ohio package was used as a starting point, but modified and tidied (somewhat) into the current com.ascert.open.ohio classes. It's a little debatable whether the OHIO model has much merit given it's lack of widespread use and adoption. As a result of this, a more specific direct API may be created in place of the OHIO model.
I'm glad you asked about that.
Ascert LLC offers a commercial NonStop 6530 datastream handling library and terminal emulator called term.6530. It is of course based around the open.term core which we maintain here, but with additions and extensions for handling NonStop 6530 terminals.

Basically, the original Freehost3270 code seemed to have a 0.2.0 version marker. Ascert moved to a 1.0 version to reflect the significant amount of refactoring. It took a couple of internal releases to get this all done to a reasonably decent level and also working on GitHub and JitPack.
