SWI-Prolog 5.6.23 and telnet

Id like to find out if SWI-Prolog 5.6.23 supports telnet (https://www.swi-prolog.org/pldoc/doc/SWI/library/prolog_server.pl)

Is there a quick way to download exactly this release – it looks like on git i have to page through all releases going back from the latest one

$ git tag | grep 5.6.23

Whether it still builds is another matter … At some point the relative location of the git submodules changed from ../packages/somepack.git to ../package-somepack.git to facilitate GitHub which does not support directories. This might make checking out this version including all packs can be a bit tedious. It is surely possible though.

i guess there is no binary available
