This is an implementation of the 5250 telnet protocol. It was originally an implementation for Linux, but it has been reportedly compiled on a number of other platforms. Contributed keyboard maps and termcap entries for FreeBSD are in this tarball as well (see freebsd/README for more information).

This, the 0.17.x series, is the development series and may cause severe headaches and stomach cramps, if only due to the quality of code :) If you are looking for a stable emulator, get the latest 0.16.x version. Even so, 0.17.x is quite stable and in production at several sites. Furthermore, for the enhanced 5250 protocol 0.17.x is required.
