Thread: All COM port detection in VC++ application

Hello,

I am new to Visual C programming and will need help pls. There is an application developed for windows which read data through serial port (COM1) and saves it in the computer. Presently, i need to extend it for the other COM ports, specifically for USB ports. How can I do so.

Any help will be gratefully accepted.

Thanks,
Emma Good

Thanks for the reply. There is a device which reads data from sensors and passes them to a computer for storage etc. The device interfaces to the computer through a serial port. The windows application is written in VC++ and is configured for COM1. I wanted to know how to extend the windows application for scanning all the COM ports of the computer.


As far as physical interfacing is concerned, I plan to use a serial to USB converter with the device and then a USB cable to interface it with the computer.

Any suggestions will be gratefully accepted.

Thanks,
