Hi,
I am trying to communicate two Com ports simultaneously.
One com port using (RS232 - RS422 - device)
Another com port using (RS232-RS422-USB-device)
When am sending a command to the two ports, only one is able to respond. Another com port is not responding.
Presently, I am using only one com port (temporarily) to make all the commands working.
And when i am trying to read from single com port configured, I am getting an error stating "VISA: (Hex 0xBFFF003E) could not perform operation because of I/O error." please find the attached screenshot
Please suggest on
1) Communication two com ports simultaneously
2) Resolve the error while reading.
Thanks
Phani
