(Standard hardware flow control Require To Send) Module output
signal, when it is high
RTS indicates that the module serial port is busy and the MCU is not
allowed to send data to the module serial port; when it is low,
data can be sent to the module.
(Standard Hardware Flow Control Clear To Send) Module input signal,
when high, indicates that the MCU serial port is busy and the module
will not send data to the MCU serial port.
CTS
indicates that the MCU serial port is busy and the module will not
send data to the MCU serial port; when it is low, data can be sent
to the MCU.
