On discussion list of this project you can find some addresses with pages with list protocol commands: • www.gadgets.co.uk/nokia21xx/index.html (Nokia 2110) • http://priv5.onet.pl/wa/junk/mbus/ (Nokia 2110 and old phones) • www.tec.puv.fi/~s98114/GSM/FBUS.html (NHx models) • http://lsc.kva.hu/dl/README.MSGTYPES.txt (NSx models) • www.venia.net/tdma/ (TDMA phones) • you can
