3.19. Behaviors of RI
AT+QCFG="risignaltype","physical" command can be used to configure RI behavior.
No matter on which port a URC is presented, the URC will trigger the behavior of RI pin.
URC can be outputted from UART port, USB AT port and USB modem port through configuration via
AT+QURCCFG command. The default port is USB AT port.
In addition, RI behavior can be configured flexibly. The default behavior of the RI is shown as below.
