Control WLED via USB?

HI, I’m new here, discovering lot of WLED features, and one fundamental for me is missing, Serial command for preset call and simple command like start stop brightness so i can piloting with existing microcontroller serial (9600 boud) 485/232/422 line, it would be nice that you can make presets and setings over web UI then just calling presset via serial presset call, if is already possible, please point me to some tutorial or serial usage… Thanx a lot !
