ANet BBS — Architecture

ANet follows a modular, event-driven architecture built on Python’s asyncio framework.

• One asyncio event loop
• One coroutine per connected user (node)
• No threads
• Non-blocking I/O everywhere

Each user connection creates a BBSSession coroutine:

• CONNECT
• LOGIN (handle/password)
• MAIN MENU
• COMMAND LOOP
• LOGOFF

State transitions are explicit and readable.

ANet supports CNet-style MCI escape codes using `\x19` as a control prefix.

Examples:

• `\x19n1` → New line
• `\x19c6` → ANSI cyan
• `\x19hc` → Clear screen

This allows reuse of original `bbstext.txt` files.
