See the chapter Supported Hardware for more information. There are also many different interface devices available that use USB port control for a full gamut of capabilities. USB-to-serial adapters can be used to provide full serial port capabilities, but be aware that not all such adapters (or their drivers) work well with N1MM Logger+.

USB port – Most computers now have multiple USB ports.

Note also that you will still need a separate virtual or hardware serial port for radio control, because radio control cannot be done from a parallel port. With one exception, USB-to-parallel adapters will not work here. In addition to controlling CW and PTT, N1MM Logger uses the LPT port to control popular SO2R control boxes, and to send band information to a band decoder for automatic antenna or bandpass filter switching.

Parallel port – Parallel (LPT) port interfacing is quite flexible.

Alternatively, USB-to-serial adapters may be used. inexpensive serial and serial/parallel port cards are available. Hardware serial ports are rapidly disappearing from most computers, but if the computer has open PCI bus slots.

Serial port – A serial port can send CW, control PTT or communicate with your radio with some radios you may be able to do all three on one port.

The program can interface with your radio using several ports from the computer. Interfacing Serial, Parallel and Sound Card Interfacing Ports Used for Interfacing
