SER_MDM_bridge.py
Jan 2009|copyright added, checked & tested
Idea for a bi-directional SER to MDM bridge, useful in serial cable to wireless
applications. It shows only the core of the implementation, other things like
module setup and GPRS and serial connections initiation and finalization must
be build around. One must play with different settings, flow control, timings
etc. to shape on different application details.
