getting the uBitx on FT8

Hi Guys,I was planning to put my uBitx on FT8 - no problem with an interface for the audio, but puzzled as to how best to drive the PTT. I've installed Ian's Firmware which seems to be CAT compliant but I can't see if it drives the PTT or if I need to install a USB - Serial interface. Interested to know how you've done it ?
