Is there a trick to use COM1 as a normal serial port?
We use USB for debugger, so no conflict there.
But I have something in mind that COM1 is used internally to send some low level debug info.
My college tries to send something via COM1, but he says that the pin only toggles on port open and close, but not on write !?
Edit: According to our schematics, P2_1 is floating.
