When initializing the modem, communication is direct via the UART channel through the ATParser channel (AT commands). At CMUX configuration, the channel for AT commands is represented by DLC_Channel (see Channel::Commands and also Channel::Notifications and Channel::Data).

Both ATParser and DLC_Channel use ATStream (in Channel) for parsing AT command. ATStream parse AT commands in terms of correctness /return (not the selected command)

below way of how ATStream parse command (especially such strange like QPING)
