Defined values:

<ind> integer type value, which shall be in range of corresponding <descr>:

0:indicator is OFF or in state which can be identified as “OFF” state

1:indicator is ON or in a state that is more substantial than “OFF” state

2:this value is more substantial than 1, and so on.

Note: If the indicator is a simple ON/OFF style element, it has values 0 and 1. <descr>:

“battchg”: battery charge level (0 - 5)

“signal”: signal quality (0 - 5)

“service”: service availability (0 - 1)

“message”: message received (0 - 1)

“call”: call in progress (0 - 1)

“roam”: roaming indicator (0 - 1)

“smsfull”: SMS memory storage status in the MT (0 - 2)

0:memory locations are available

1:memory full

2:one SMS has been received in Service Center (SC) but the sms storage where this SMS tried to be stored is full.

Multiplexing Mode: +CMUX

Description: This command is used to manage (enable or disable) the 3GPP TS 27.010 multiplexing protocol control channel.

This command allows the multiplexing of 4 logical channels on a single UART. Two UARTs are available on the G2150I, but multiplexing can only apply to one. The client application may handle, by this means, up to 5 channels (4 logical multiplexed channels on a UART and 1 physical channel on the other UART).

Notes on speed and autobauding:

•The speed of the response is the same that the one of the received AT+CMUX command (prior to entering <mode>).

•It is recommended that, whenever the multiplexer control channel is released, the modem should assume an interface rate for autobauding purposes, irrespective of any previous higher speed selected.

•If a +CMUX command is issued while in any multiplexer mode, then that +CMUX
