# dos.library — AmigaDOS Overview
## Section Index
| File | Description |
|---|---|
Phase 1 continued: serial, input devices + README indexes 10_devices: - serial.md: expanded with DB-25 pinout, custom chip UART registers, baud rate calculation table, open/configure/read/write patterns, serial debugging (KPrintF/Sushi) - input.md: expanded with handler chain architecture diagram, InputEvent struct, event classes table, qualifier bits, custom handler with key remapping, event consumption/blocking, synthetic event injection, Commodities Exchange Updated indexes: - 07_dos/README.md — enriched descriptions for all files - 10_devices/README.md — enriched descriptions for all files
