MAP27 Trunked Radio Protocol

(C) 2005 Hernan Monserrat, GNU General Public License version 3

This project implements a protocol converter between a HAYES style subset of ASCII commands to/from MAP27, a binary Radio protocol for Trunked Radios on MPT1327 networks.

The core implementation follows the MAP27 specification version 1.5 year 1998. All the names and conventions used in the source code follow the specs convention. (not so good programming convention practices but good enough in order to follow the specs name convention).

The idea of the code is to be embeddable and portable, keeping in mind low-end 8 bit microcontrollers with low memory resources.
