3-1 Serial Port
The COM port serial will change bases on the installation order of the 3G/4G device and
the FTDI USB serial port device, which affect the serial port access of RS485/RS422.
The following figure shows the serial port identifier after installing the 3G/4G driver first
and then installing the USB serial port driver.
COM7/COM8/COM9/COM10 show as USB Serial Port.
COM3/COM4/COM5/COM6 show as Quectel USB AT Port (3G/4G serial port). COM6 is
Modem data serial port.
The following figure shows the serial port identifier after installing the USB serial port
