Re: Diavolino Serial Com

I guess I’m not familiar with a “TTL level COM” port, but if it exists, then there should be some way to hook it up.  The FTDI adapter is not strictly necessary, and there are a great many articles out there about programming an Arduino directly from an RS-232 port.   Depending on exactly what your computer has, you may need a level adapter or polarity adapter in order for everything to work correctly.
