Set command is used to enable/disable the 3GPP TS 27.010 multiplexing protocol
control channel.
Parameters:
<mode> multiplexer transparency mechanism
0 - basic option; it is currently the only supported value.
<subset>
0 - UIH frames used only; it is currently the only supported value.
<port_speed> transmission rate
5 - 115 200 bit/s (default)
<N1> maximum frame size
1-1509, the default is 121
<T1> acknowledgement timer in units of ten milliseconds
1-255: where 10 is default (100 ms)
<N2> maximum number of re-transmissions
0-100: currently only the range 0-5 is supported, the default is 3
<T2> response timer for the multiplexer control channel in units of ten milliseconds
2-255: where 30 is default (300 ms). Note: T2 must be longer than T1.
<T3> wake up response timer in seconds
1-255: currently not supported, in case of read command 0 is returned
<k> window size, for Advanced operation with Error Recovery options
1-7: currently not supported, in case of read command 0 is returned
Note: all the CMUX protocol parameters are fixed as defined in GSM07.10 and
Read command returns the current value of <mode>, <subset>, <port_speed>,
<N1>, <T1>, <N2>, <T2>, <T3> and <k> parameters, in the format:
+CMUX: <m

Test command returns the range of supported values for parameters <mode>,
<subse

Read ICCID - +CCID
Execution command reads on SIM the ICCID (card identification number that
provides a unique identification number for the SIM)
Test command returns the OK result code.
