COM port test with "No operations reported in timeout period"

[quixant_jacky]

115200, 8 com ports and get the error message "No operations reported in timeout period".
in 1 hour.

9600, 8 com ports and get the error message "No operations reported in timeout period".
in 16 hours.

BTW, as running the third party com port test tool (PCommpro by Moxa) with 115200 8 com ports and it's no problem over 48 hours.

I run BIT V7.1 and use the microsoft standard serial communication driver.

Thanks

What version of V7.1 are you using. If you aren't using the latest build can you try the latest V7 build or V8.

What is the hardware involved?

Are you running any other tests at the same time?

Are you using our serial port loopback plugs?

What version of Windows are you running? And it is 32bit or 64bit?

Did you check the BurnInTest log for any other errors?

Did to try the card in another machine?

Are you using the latest device driver for the serial port card?
