Sorry to have mixed "ez-Dos" and "ez-Nos"... Thank you very much for the pointer and the fresh archival on GitHub. It looks like that network stack contains some interesting stuff to have a look on for the protocol implementation. I keep it under the hand. But after a quick parse, it looks also like that stack does not contain any ethernet card driver, just the layer to connect through the old serial line modems (SLIP and so on). Reminds me the times of the singing modems at home... tuuut-tuuut-pouic-diii-daaa-criiiicriiiicriiii... :-) MFLD ---------- Forwarded message ---------- From: GOliath Keet <goliath.keet@xxxxxxxxx> Date: 2017-01-28 18:23 GMT+01:00 Subject: Re: Elks networking To: Marc-François LUCCA-DANIAU <mfld.fr@xxxxxxxxx> The original Author has open sourced this code, and has corresponded with me via email and reassured me, that he would like to see it used. https://github.com/parabyte/ez-nos/archive/master.zip Its like a unix environment for dos. i hope something in there is useful for someone.
