Table 4.2:	Summary of AT commands with Different Behavior in Multiplex Mode
Command		Description
AT\Q		It is recommended to use hardware flow control (AT\Q3). XON/XOFF flow control
		(AT\Q1) is not supported in Multiplex mode.
		See note regarding AT\Qn settings stored with AT&W if Multiplex mode is active.
AT&V		Different default configurations on channels 1, 2 and 3.
AT&W		Different user profiles can be stored on each channel.
AT+IPR		Before you start Multiplex mode, it is recommended to set the ME to 57600 bps
		(minimum should be 4800 bps). For GPRS we suggest to use 115200 bps or
		230400 bps.
		In Multiplex mode, the write command AT+IPR=<rate> will not change the bit rate
		currently used, but the new bit rate will be stored and becomes active, when the
		module is restarted.
AT+IPR=0		Multiplex mode cannot be activated while autobauding is enabled.
AT+CALA		On each channel an individual <text> message can be stored. but only one time
		setting applies to all channels. This means an alarm <time> set on one of the
		channels overwrites the time setting on all remaining channels. Therefore, the total
		number of alarm events returned by the read command AT+CALA? will always be
		<n>=0, no matter whether individual text messages are stored.
		When the alarm is timed out and executed the ME sends the URC only on the
		channel where the most recent alarm setting was made. The alarm time will be
		reset to "00/01/01,00:00:00" on all channels.
AT+CMEE		Presentation mode can be separately configured for each channel.
AT+CNMA		If Multiplex mode is activated the +CNMI parameter will be set to zero on all chan-
		nels, if one channel fails to acknowledge an incoming message within the required
		time.
AT+CNMI		Phase 2+ parameters can only be used on one channel. The parameter for <mt>
		and <ds> on the other channels have to be set to zero. If either a SM or a Status
		Report is not acknowledged, all +CNMI parameter will be set to zero on all chan-
		nels.
AT+CFUN		If the ME is in Multiplexer mode, it is not recommended to activate SLEEP mode
		with AT+CFUN=<fun>. The best approach to properly control SLEEP mode in this
		case is to issue the PSC messages described in [5], Section "Power saving control
		(PSC)".
AT+CPMS		Parameter <mem3> will be the same on all instances, but the settings of <mem1>
		and <mem2> may vary on each instance.
AT^SSDA		If one instance is set to <da>=1 and <mt>=1, then all other instances must be con-
		figured for <mt>=0.
