Hi,
In fact, each character of the data I receive represents two
values, the sensitivity of marks. One is correct, but the
other is unreasonable. Therefore, I said the data was wrong.
Besides, the MSCOMM32 problem was mentioned for many times
in the forum in Taiwan. And, the answers for the problem I
had tried were wrong. I don't know whether the problem was concerned
with the VFP and VB of the chinese version.(Some top-level programmer
had ever said...)
Thanks for your help and I will continue to try other methods.
