Defined values:

<mode> multiplexer Transparency Mechanism 0: Basic option

<subset> This parameter defines the multiplexer control channel setup. A virtual channel may subsequently be set up differently but if there is no settings negotiation, the virtual channel will be set up according to the control channel <subset> setting.

<port_speed> transmission rate

1:9600 bit/s

2:19200 bit/s

3:38400 bit/s

4:57600 bit/s

5:115200 bit/s

Note:

•If port speed is not configured by the at+CMUX command, the current <port_speed> is the same as that displayed by at+ipr? command.

•If port speed is configured by the AT+CMUX command, the AT+CMUX port speed setting is erasing the AT+IPR port speed

•At the end of the CMUX, the <port_speed> displayed is the same as that
