After finding the keyword, wait requires the receive buffer to stay quiet for ~300ms (no new bytes) and consumes up to the LAST occurrence. This rejects matches on echoed command prompts (e.g. 'SVOS> help') mid-output, preventing the script from racing ahead. Applies to all wait-based loops without per-command markers.
- Add TeraTerm-compatible sprintf2 (C printf formatting into a string var)
- Fix SVOS power-cycle script racing ahead by gating prompt waits behind output-completion markers
- Bump version to 0.1.2; docs and README updates
