How to change the system baud rate for windows OS

Anonymous

Hi,

I am using SerialPort class. There is a property name BaudRate. And I am setting the new value like (9600, 19200, 38400 etc).

SerialPort mySerialPort = new SerialPort("COM4");

mySerialPort.BaudRate = pBaudRate; //38400

If My old baudrate value is 19200 and I have set new baudrate with 38400. then GPS data is not coming on new baudrate. It still coming on old baudrate.

Also not getting there this value is setting.

Kindly help on this.

Thanks,

Arvind

Hi @Arvind Kumar, Welcome to Microsoft Q&A,

Your problem seems to depend on your hardware. Maybe you can get support based on your third-party hardware.

Hello Jiale Xue,

I am following the MSDN post (https://learn.microsoft.com/en-us/windows/win32/devio/configuring-a-communications-resource) to change the baud rate of the comport.

Able to get the existing baud rate of the comport with this (GetCommState(hCom, &dcb) ) method. After setting baud rate using SetCommState(hCom, &dcb) no error comes but not receiving data on updated baud rate .

Kindly help on this.

Thanks,

Arvind

You need to make sure your device can support such a high rate.

The Objective C++ Win32 documentation is only set at the code level, and it ultimately depends on your device.
