- Detect CTS at startup to ensure it is asserted. If not, disable hardware flow control to avoid stalling the console at boot. Only for UART driver because this is the only place it is currently relevant.
- Based on reports from Martin R, the FDC detection algorithm has been updated to try reading the FDC MSR register twice to try and get the desired value of 0x80.
- Dan Werner's ESP board for Duodyne is working well, so the default Duodyne config has been changed to automatically detect this board.
