RS232: Invalid Communication Handle
While a RS232 port was accessed an invalid handle was or is used. This could indicate that a port is trying to be opened which is not present (any more).
Solution
- Ensure that no other program is using the same COM port
- For USB <=> RS232 devices: Ensure that the device is connected to an USB port, and that the device is powered on.
