My device uses USB for deployment and debugging but it has a serial port as well. How can I use the serial port instead?
You need special port for such change so contact your porter if they have or would create one for you.
Can the .NET Micro Framework application update itself?
No. The application has no access to the assembly deployment area of memory.
