- Under Microsoft Windows, the microHAM USB Device Router can create/map the USB III to separate virtual serial ports for control, CW, and PTT. With OS X and LINUX the control, software CW and PTT outputs are provided on a single TTY device using native drivers for that operating system. The USB soundcard uses native drivers for each operating system.
