The parallel and serial port device file names are system specific.
macOS has no default serial port names, but available ports can be
found under /dev/cu.*. Please take note AVRDUDE does not
support parallel port programming under macOS.
The following table lists the default names for a given system.
| System | Default Parallel Port | Default Serial Port |
| FreeBSD | /dev/ppi0 | /dev/cuad0 |
| Linux | /dev/parport0 | /dev/ttyS0 |
| Solaris | /dev/printers/0 | /dev/term/a |
On FreeBSD systems, AVRDUDE uses the ppi(4) interface for accessing the parallel port and the sio(4) driver for serial port access.
On Linux systems, AVRDUDE uses the ppdev interface for accessing the parallel port and the tty driver for serial port access.
On Solaris systems, AVRDUDE uses the ecpp(7D) driver for accessing the parallel port and the asy(7D) driver for serial port access.
