Hello,
You get error 16400 (x4010)probably due to bad programming. This error will be caused when break conditions exist on the serial port before a LabVIEW program starts and initializes the serial port.
You can simulate this problem by following these steps:
1. Use a null modem cable to connect one COM port to another.
2. Use the Serial Port Break.vi to send a break to a COM port.
3. Run the example Serial Read.vi and this error will occur.
The Serial Port Initialize VI clears the serial buffer, but does not clear the break condition on the serial port. When a LabVIEW VI is subsequently run, error 16400 or 16408 occurs indicating a break condition.
To clear the break condition you need to complete the following steps:
Be sure that when the VI s
tarts, you close the serial driver using Close Serial Driver.vi found in C:\Program Files\National Instruments\LabVIEW\vi.lib\instr\sersup.llb.
Initialize the serial port using the Serial Port Init.vi.
This will close the serial driver, initialize the serial port, and effectively eliminate the break.
I hope this helps.
Best regards.
