Comment out serial ready line for normal operation

Normal operation means not connected to a serial port.

- If you have that line in, Clyde won't start executing until the Serial Monitor is opened (bad)
- If you don't have that line, Clyde starts up and runs just fine.

So, if you want to talk to Clyde,
- If you want to send serial commands to Clyde, you must have that line in your file
- If you don't have that line, serial communications are unreliable
