I trying to build a software in C# on Windows 10, that send SMS with an usb GSM Modem,
the issue I am facing now, is to to identify the COM Port the usb GSM Modem is connected on, to use the right one for sending routine.
can anyone help me to get the COM Port number for an usb port on Windows 10?

I want to know the way BLED112 smart bluetooth dongle makes communication between Windows, and BLE devices. I mean to say that I am aware it makes virtual COM ports. But the question is that it makes the COM port for each of the BLE devices connected with it. Or does it makes only one COM port.
Also, do i need to write some special code for bluetooth connection in Windows with this dongle. Or any arbitrary code will run with this dongle.
Thanks in advance.
The BLED112 is a USB Bluetooth LE dongle that contains a Bluetooth radio with its own Bluetooth stack and provides an interface to interact with the Bluetooth radio via the COM port.
With this concept, you can, for example, connect Bluetooth LE devices with Windows 7 and earlier versions. These Windows versions do not include a Bluetooth stack that supports Bluetooth LE.
Therefore the BLED112 has exactly one COM port for control and communication with the Bluetooth LE hardware on the dongle. With the right programming, it is able to connect to multiple Bluetooth LE devices at the same time.
I am quite new to KaiOS and was wondering if it is possible to build an app that sends / receives serial communications (for instance communicate with Arduino) over a physical cable connected to the phone.
I am currently doing it on Android using this library https://github.com/mik3y/usb-serial-for-android, and would love to do it on KaiOS.
I looked at the permissions and see that there is nothing related (https://developer.kaiostech.com/core-developer-topics/permissions) but I did not find any info saying that it is possible (or not possible) to do it
If not possible, any idea of how to do Serial communication between a feature phone and an Arduino is welcomed !
Thanks for you help !
Nope. KaiOS phones do not support USB Host mode.
I've tried plugging USB mouse and keyboard in Nokia 2720 using USB OTG cable, the phone did not even provide +5V power to the USB port (my keyboard lights up LED if I plug it into USB charger)
Likewise, Bluetooth is limited to headphones, my Bluetooth mouse and Bluetooth gamepad did not work.
What is needed for the physical USB connection between two Windows computers for communication between their virtual serial ports?
Should I use USB/serial adapters?
I am building a .NET terminal app on Windows 10 Pro computer that must use a virtual serial port for communication through a USB connection to the virtual serial COM port at a Windows 7 Pro computer that is running the terminal app on .NET.
The terminal app is the PortChat example app from MSDN's serial port documentation.
PURPOSE: I need to test a serial communication .NET app on Windows 10 that will eventually communicate with an embedded STM that is presently unavailable .
You need two usb/Serial adapters and connect them to each computer.
Then connect those two serial interfaces together with a Null Modem Cable.
I have written a window service using c++ with win32 apis, which will notify whenever USB device is connected to computer,using SERVICE_CONTROL_DEVICEEVENT.
Suppose my computer has both USB3.0 and USB2.0 port, How would Service came to know whether device is connected to 3.0 or 2.0 port using this machanism ?
Kindly help me to solve this problem.
