Bitsy boot code v1.75 corrects an issue with noise on inactive serial ports (details). This problem isn't an issue for all applications, and doesn't show up on all Bitsy systems.
To update your system with the new boot code, click on "CE image and boot code downloads..." above and download the boot code for your device. Follow the instructions included in the ZIP file.
The Serial 1 DTR line and the LED are controlled by the same StrongARM GPIO line (GP20). To control the LED, open COM1: and set the state of the DTR line on(DTR_CONTROL_DISABLE) or off(DTR_CONTROL_ENABLE). The LED1: driver is not available in current builds of CE for the Bitsy.
See rev 3 of the Heartbeat.exe application for an example of how to do this.
