"Serial.available" always returns true even if no data

I have got this code that works using Arduino IDE, but fails in Visual Micro.

Code
Select All
        if (Serial.available())
	{
		for (int i = 0; i < 128; i++)
			last_command[i] = '\0';

		char end_char = '\n';
		Serial.readBytesUntil(end_char, last_command, 512);
		return true;
	}
	else
	{
		return false;
	}


I use Arduino ONE, IDE Arduino 1.6 and no programmer to upload.

Thank you.

Hi,

I think this is because the debugger is active and your code shares the serial port with the debugger.

1)
You can switch the debugger to using a different serial port or use one/two digital pins. See this article for more info.

Or 

2)

You can switch the tool bar from "Local windows debugger/Debug" to "Release". Then upload and Visual Micro will work the same as the Arduino ide .

...

Let me know if still an issue?
