Close the Debug Terminal before reprogramming, disconnecting, or reconnecting your board to
the USB port. If you forget to do this, you may receive and error message and/or freeze the BASIC
Stamp Editor when you next try to download a program. If this happens, close the BASIC Stamp
Editor with the Task Manager (Ctrl+Alt+Delete). If you do this repeatedly, you may need to reboot
your computer and/or reinstall the USB VCP drivers.
If your BASIC Stamp is actively transmitting data via its port (using the DEBUG or SEROUT 16
commands) and you disconnect and reconnect your board, the BASIC Stamp Editor may
misidentify it. To avoid this, turn off power to your board before reconnecting it to your PC.
