Middleware for controlling an XBee module from Ruby. Series 1, Series 2 modules supported in AT (Transparent) or API (non-escaped & escaped) mode. Examples included how to use including Over-The-Air application firmware upgrade for programmable XBee modules.

A simple gem for XMODEM client and server application. Forked from modem_protocols and made to work with newer Rubies. Today the XMODEM protocol is widely used in embedded systems for OTA application firmware transfer.
