Improved Layer-2 Protocol by Nino Carillo, KK4HEJ
page modified September 17, 2020
This page has a copy of a PDF describing the protocol implemented in IL2P mode of the NinoTNCs.
As of the change date of this web page, the IL2P mode is supported in one model and 3 versions of the NinoTNC.
Each of those versions, having conducted transmissions in IL2P mode, will send out an AX.25 beacon identifying the callsign used for the TNC and giving the shortened URL leading to this page.
Feel free to download the IL2P specification just below.
You are encouraged to consider implementing the spec and to ask questions on the firstname.lastname@example.org email reflector
