avrdude ser_open() can't set com-state

Maybe a Windows driver problem. Do your uno and nano use a ch340? (It is the component translating USB to uart (serial pins of atmega328). Windows has no software way to differenciate boards using ...

Upload a .hex file, using a standalone ISP, without overwriting bootloader

To preserve the bootloader, you should use the -D option in the ISP command line just as it was used in the bootloader upload command line. This will disable usage of full-chip erase. I expect you ...

When using Arduino Uno as ISP does "Yikes! Invalid device signature" mean a bad connection, bad config, or bad version of avrdude?

I had exactly this problem. If the ATtiny is set for external clock, then the ArduinoISP will not be able to program it without an external crystal. Connected a 16 MHz crystal and 2 capacitors ...

Relationship between avrdude's "programmer" and bootloaders

If you are using the bootloader, you are not using a programmer. The programmer, when used, is connected to the ICSP pins on the Arduino. The bootloader however expects a well-defined sequence of data ...

Are intel hex files converted into a binary format before they are written to Atmega's flash?

Yes, the hex codes in the .hex file are read in by avrdude (or other programs) and written to the MCU in binary. A small microprocessor would not be able to read ASCII format commands. See my answer ...
