Error while sending data to the com port (on Windows 10)

[yzstd88]

Hi Passmark

We find an issue that when we test several com ports at the same time. Burn-in test V8.1 (build 101 will show "Error while sending data to the com port "

Please refer to the attached picture. But this issue only occurs on Win 10 . And the issue is easy to duplicated when we test more than 1 COM ports and set baud rate to 115200(max) at the same

time

But this issue does not occurs on Win7 Win8 . Do you know if there is compatibility issue between Burn-int test V8.1 and Win 10?

Thanks

Yes, BurnInTest is compatible with Win10. We aren't aware of any serial port issues in Win10.

Hi Passmark

Have you ever tried to test several com ports on window 10( EFI mode , not legacy mode) ?

So far our experiments shows that the issue only occurs on window 10 EFI mode .Legacy mode can pass the test

Thanks

Yes, we are not aware of any issues.
UEFI BIOS should not effect the serial port.
Maybe there is a bug in your BIOS?
