基于事件的visa 串口通信的奇怪问题

[Alexleung]

我是新手！我用下列vi用于与串口助手收或发都没有问题，但是用单一usb串口（prolific 驱动）环回就出错，Error -1073807298，不知如何解决，请高手赐教！

This issue can be caused because some third party devices do not implement all serial settings on their USB-Serial adapters. To avoid the problem, do not use the VISA Configure Serial Port VI in your program. Instead use a VISA property node to set only the supported properties.
