-"""Peripheral tools for interacting with DOSBox-X I/O.
-
-These tools simulate user input and capture output via QMP:
-- Screenshots: Capture display state
-- Keyboard: Send keystrokes to DOS programs
-- Mouse: Move cursor and click
-- Serial: Send data to COM ports (for terminal programs)
-- Joystick: Game controller input
-- Parallel: Printer port communication
-- Clipboard: Copy/paste between host and DOS
-
-All peripheral tools use QMP (port 4444), not GDB.
-
-Screenshot workflow:
-1. screenshot() - Capture current display, get filename
-2. Read dosbox://screenshots/{filename} resource for image data
-3. Or use dosbox://screen resource for live capture without saving
-
-Keyboard input examples:
-- keyboard_send("dir") then keyboard_send("enter")
-- keyboard_send("ctrl-c") for interrupt
-- keyboard_send("alt-x") for menu shortcuts
