Which node are you reporting an issue on?
I encountered an error with the node-red-node-serialport module while using the serial control node to open and close communication with a product.
What are the steps to reproduce?
1) Initial Configuration
I configured the COM port as shown in the image above with the following settings:
Split input after a timeout of 200ms
Sequence
Close COM port (close com - works correctly)
Open COM port (open com - works correctly)
Send serial commands using the serial request node (send serial commands - works correctly)
Close COM port (close com - works correctly)
Open COM port (open com - works correctly)
2) Problem with New Configuration
When I used the following configuration:
Split input into fixed lengths of 30000 chars
and repeated the same steps, I encountered an error at step 5:
Close COM port (close com - works correctly) Open COM port (open com - works correctly) Send serial commands using the serial request node (send serial commands - works correctly) Close COM port (close com - works correctly) Open COM port (open com - error: "TypeError: newline.substr is not a function")

What happens?
error: "TypeError: newline.substr is not a function"
What do you expect to happen?
Close COM port (close com - works correctly) Open COM port (open com - works correctly) Send serial commands using the serial request node (send serial commands - works correctly) Close COM port (close com - works correctly) Open COM port (open com - works correctly) Send serial commands using the serial request node (send serial commands - works correctly) Close COM port (close com - works correctly)
