Do everything needed to connect the modem. Dictionary of properties needed to get the modem connected. Each implementation is free to add it's own specific key-value pairs. The predefined common ones are: 'pin' : string 'network_id' : string (GSM/HSPA only) 'band' : uint 'network_mode' : uint 'apn' : string (GSM/HSPA only) 'number' : string 'rm-protocol' : uint (CDMA/EVDO only) (1 - Relay, 2 - Network PPP) Get the modem status. Dictionary of properties. Each implementation is free to add it's own specific key-value pairs. The predefined common ones are: 'state' : uint (always) 'signal_quality' : uint (state >= registered) 'operator_code' : string (state >= registered) 'operator_name' : string (state >= registered) 'band' : uint (state >= registered) 'network_mode' : uint (state >= registered)
