@BillyONeal
Maybe it is due to my README file, it is not writed with English. So not matched by Bing/Google(English).

The last item of first page with google serch (English) is itas109/CSerialPort. URL is https://gitee.com/itas109/CSerialPort. It is also my project, mirrorring of https://github.com/itas109/CSerialPort.

https://cn.bing.com or https://www.google.com.hk could find itas109/CSerialPort.

Also matched on github. itas109/CSerialPort is the first.

The language thing is a good point and something I had not considered. Will double check in the morning when not about to go to sleep :). Have a great day!
