-- Notes, bugs and a todo list for AT command compatible modems --

* Notes *

General PDU documentation can be found on:
	http://www.siemens-mobile.de/pages/wm/downloads/m20_sms.pdf
General AT commands documentation can be found on:
	http://www.siemens-mobile.de/pages/wm/downloads/tc35_at_e.pdf

Although this documentation is for Siemens devices, your modem will probably
support some subset (or superset?) of it. Official standard document could be
probably also found in www.etsi.org library.
