I'm developing a test using direct IO controll to a serial device. I have the serial port configured and can send commands and read data back from the UUT. The problem I have is that when I power down the UUT (which I have to do several times during the test) it doesn't re-connect to the serial port. I have to shutdown and restart my VEE program to establish the connection. Is there a way to re-establish a serial connection in VEE.

No one else has this question

Try re-open the port before you try to send/read data from it.

I have a program that it uses serial port to communicate through Teraterm, and it required me to send the enter command twice to refresh the page before I can get any data, maybe that's your case?

I tried with USB device, after I shut down the device, make sure there is no attempt to talk to the device at all. After the device is back, only continue to talk the device. Something like below.

Hopefully it is the same for serial device.

Hope this helps,
