<p class="MsoNormal"><span lang="EN-US">As an Erlang newbie, I have not a complete idea of how should I implement these features. Currently, I just found something like the Pyrlang and the Erlport. They used someway like the EPMD and the Erlang port protocol
(I am not sure whether they using the same erlang technology so that I pointed out both). However, both of them start from older OTP versions (like OTP 19 in 2016) and the Erlport seems stopped years ago. So I am not sure is it appropriate to use the two projects
for reference. <o:p></o:p></span></p>
