Oooops, I've forgotten something important: Before you can configure
your GSM modem you have to supply your PIN or SuperPIN to register to
GSM service! If you using the modem for the first time, check provider
 settings.
When you initalizing your link using PPP+LCP you also have to
activate/configure some link features like LPC echos, magic number
support, header compression and/or your ASYNC map. Make sure that all
the special characters (e.g. +) are substituted by your ASYNC map or
you might become very funny and unexplainable effects of system,
especailly with your modem connection!
