Q2406B, openat and 27.010



I am trying to evaluate how to use protocol 27.010 with Q2406B and open at. I know that using AT+CMUX, this protocol is enabled, so I suppose that ADL_PORT_UART_X_VIRTUAL_BASE ports are created (four if I am not wrong… this means one control channel an three data channels?).

But the question is… Are all channels automatically created or should I send SABM frames… to open them?

Also… How do we select the values for the DLCI, or are the DLCIs set to a fixed value (channels 1-3)?
