+# console.device — Text Terminal I/O
+
+## Overview
+
+`console.device` provides ANSI-compatible text rendering into Intuition windows. It translates raw keycodes to ASCII and supports a rich set of escape sequences for cursor positioning, colour, and text formatting.
+
+---
+
+## Opening
+
+```c
+struct IOStdReq *con = CreateStdIO(port);
+con->io_Data   = (APTR)win;  /* the Intuition Window */
+con->io_Length = sizeof(struct Window);
+OpenDevice("console.device", 0, (struct IORequest *)con, 0);
+```
+
+---
+
+## Common Escape Sequences
+
+| Sequence | Description |
+|---|---|
+| `\033[H` | Home cursor |
+| `\033[nA` | Cursor up n lines |
+| `\033[nB` | Cursor down n lines |
+| `\033[nC` | Cursor right n columns |
+| `\033[nD` | Cursor left n columns |
+| `\033[y;xH` | Move to row y, column x |
+| `\033[J` | Clear to end of screen |
+| `\033[K` | Clear to end of line |
+| `\033[nm` | Set graphics rendition (colour/style) |
+| `\033[0m` | Reset attributes |
+| `\033[1m` | Bold |
+| `\033[3m` | Italic |
+| `\033[4m` | Underline |
+| `\033[30–37m` | Foreground colour |
+| `\033[40–47m` | Background colour |
