Hello,
the Erlang command line interface (OTP version) is available on Github: https://github.com/josemic/Erlang-command-line-interface_otp
This is a telnet commandline server written in Erlang using OTP libraries. It provides features such as command-completion, command-abbreviation, command-help, reading/writing commands from/to file and modular command-registration.
Its behaviour is kept similar to the well known, C-written, OpenBSC telnet command line server.
It is intended for future inclusion into Osmocom's Erlang projects.
The installation instructions are found in the github wiki.
Cheers, Michael
