Com Port connection using USB in C++
Com Port connection using USB in C++
- 0Hi,
I am a new coder in Visual C++. I have coded in Visual basic and am familiar with the concepts of object orientated programming. I am having some problems opening a com port using C++ through a USB device. The Com port is created and exists in the Control Panel under modem. The specification are there as well.
The question, is there a class that i can use to create a connection to this COM port to the device? Can anyone provide me with some sample code for creating a com port connection through USB in C++?
Any assistance will be appreciated.
Regards
Dal

- 0Hi Del,
Comport connection creation through USB is done using regular comports. You have to install drivers provided with serial/usb cable (or download one). Then you can check for COM port number under Ports (COM and LPT) in Device Manager. (tip: unplug cable and plug it in again to be sure you got the right com port number).
Then you can try connecting by using this "library", for example:
http://www.codeproject.com/KB/system/serial.aspx?display=PrintAll&fid=1996&df=90&mpp=25&noise=3&sort=Position&view=Quick&fr=226&select=1241634
If you have some problems with COM ports greater than 9 (two digits) try to manually set COM port number to 1-9.
