Urgent - Problem with Modem Baud Rate

[ram19382]

Dear all,

I developed a project for PC-Serial port communication in VC++. In that i opened the Comm port, it is opening with default port setting values like Baud Rate = 9600, DataBits = 8 & etc.

The exact problem is,
When i connect the Modem using Serial-Usb converter the Baud is to be set as 115200. In hyper termal with the Mentioned Baud Rate i tried modem is working Fine.

In my project the comm port is opening with default values. But what i need is, it should be open with 115200. Moreover i tried once the port was opened i used the function setcommstate() to change the values. It is not reflecting.

The reason behind this is, the Baud Rate is to be set is 115200, but in my application it is opening with 9600 as Default.
So what ever the command/ settings if i give to modem it is not working. In other way we can say for any operation the modem is not responding.
Because it was opened with 9600 as a Baud Rate.

I don't how this VC program is taking the Baud Rate 9600 as Default.

Please let me know how to solve this problem. Its Very Urgent.

Hello Ram,

In the object, there is a property called DeviceSpeed. Use this property to select another baudrate.

Hi Leon

Thanks a lot.

I'm not able to your point. In VC++ their is no function called as DeviceSpeed. If possible let me know more detailed.

Thank u.
