MUX UART Port Speed
Auto baud rate detection is disabled in the MUX. To set the UART baud rate, the G24 uses the 
<port speed> parameter in +CMUX command. If the parameter is absent, the MUX uses the same 
baud rate that was in PREMUX state.
+CMUX, MUX Startup Command 
This command is used to enable/disable the GSM MUX multiplexing protocol stack. When the 
G24 receives a valid +CMUX command, it returns OK and changes its state to MUX-Init. If the 
parameters are left out, the default value is used.

+CME ERROR: <err>
The Set command 
requests the G24 to 
open the MUX stack 
with various 
parameters. This 
command works only 
in PREMUX state.

+CMUX?
+CMUX: <mode>, [<subset>],

<T2>, <T3>+CME ERROR: <err>
The Read command 
displays the current 
mode and settings. This 
command works only 
in MUX state.
Test
+CMUX=?
+CMUX: (list of supported 
<mode>s),(list of 
supported<subset>s),(list of 
supported <port_speed>s),(list 
ofsupported <N1>s),(list of supported 
<T1>s),(list ofsupported <N2>s),(list 
of supported <T2>s),(list ofsupported 
<T3>s),(list of supported <k>s)
The Test Command 
displays a list of 
supported modes and 
parameters. This 
command works in 
both PREMUX and 
MUX states.
