Hi All,
I am attaching my LabVIEW 2017 files for reference.
I am currently facing an issue with serial communication over a virtual COM port. My setup involves sending specific command frames based on user input and at periodic intervals:
Commands:
- Motor ON:
4153 0703 7A 0118
- Motor OFF:
4153 0703 6B 0109
- Speed:
4153 0701 3E 00DA
These three commands are transmitted for approximately 1 ms when a button is pressed.
- Data Request:
4153 0705 8C 012C
This command is sent every 20 ms.
Issue:
When the receiver end is connected and actively communicating, everything works as expected. However, when the receiver end is OFF or disconnected, I am unable to observe any transmitted data on the virtual serial port.
Expected Behavior:
I would like to continuously monitor the transmitted data on the virtual COM port regardless of whether the receiver is connected or not.
