Making Huawei E3272 Modem Work as a COM Port
In this article, we will discuss how to make the Huawei E3272 LTE USB modem work as a COM port, allowing it to function similarly to a network card (WLAN) using HiLink software. This is especially useful for those who are unable to see the device's COM ports, as was the case with the older Huawei models.
Background
The Huawei E3272 is a popular LTE USB modem, also known as a "dongle." It uses HiLink software to connect to the internet, but some users may prefer to use it as a COM port instead. This can be useful for a variety of applications, such as using the modem with custom software or scripts.
Finding the COM Ports
To use the Huawei E3272 as a COM port, you will first need to locate the device's COM ports. This can be done by following these steps:
- Connect the modem to your computer using a USB cable.
- Open the Device Manager on your computer.
- Look for the Huawei E3272 modem in the list of devices.
- Expand the modem's properties by clicking on the "+" sign next to it.
- You should see a list of COM ports that are associated with the modem. These will typically be in the form of "COMx" where x is a number.
Using the COM Ports
Once you have located the COM ports for the Huawei E3272 modem, you can use them in a variety of ways. For example, you can use a serial terminal program, such as PuTTY or minicom, to connect to the modem and send commands. This can be useful for debugging or configuring the modem.
You can also use the COM ports in custom software or scripts. For example, you could write a script that sends an AT command to the modem to check its signal strength. This could be useful for monitoring the modem's connection in real-time.
Troubleshooting
If you are having trouble using the COM ports for the Huawei E3272 modem, there are a few things you can try:
- Make sure that the modem is properly connected to your computer.
- Check that the COM ports are enabled in the Device Manager.
- Try using a different serial terminal program or custom software.
- Consult the modem's documentation or contact Huawei support for further assistance.
