The following table shows the +CMUX parameters.
Note:
Due to non-ERM, the <k> parameter is not supported.
MUX Modes
The <mode> parameter in the +CMUX command determines whether the MUX protocol works 
in Basic mode or Advanced mode, including the transparency mechanism. When the G24 
changes states from PREMUX to MUX-Init, the G24 opens the MUX stack in the selected mode.
In Advanced mode the following requirements apply:
The length field is no longer be a part of the new frame structure.
A transparency mechanism.
XON/XOFF flow control is available.
