EHS6T-USB Connection USB COM Problem | Telit Cinterion IoT Developer Community

I have purchased a Gemalto EHS6T-USB module to perform some call automation and SMS messaging operations. Unfortunately, I have not been able to establish communication with the device via USB COM because the device, although it starts, stops printing the following two lines in the terminal:
^ SYSLOADING
^ SYSSTART
I have used different terminals, such as PuTTY, TeraTerm and Docklight, obtaining the same results in each one, in addition to trying different configurations and flow controls. Below, I show the settings I've used:
I have also tried different USB ports on my computer, as well as tried on another computer, getting the same results. The operating system I use is Windows 10 Pro.
I understand that it should print the following:
This is my first time using Gemalto devices, if additional settings have to be made before attempting to connect I would greatly appreciate your workarounds, to determine if it is a factory issue of the device.
Hello,
In case of USB you should find 6 COM ports in Device Manager in Windows under Ports. Please note that not all ports can be used for AT commands - please try more than one. If you see the ^SYSLOADING and ^SYSSTART URCs the port is correct. For USB the baudrate setting is not relevant. Please also note that to send an AT command you need to terminate it with <CR> character. Please configure your terminal program to add this character.
