# SERMO-BBS
A telnet server that drops every caller into a simulated PC. It POSTs, boots,
loads **SERMO-DOS**, and leaves you at a `C:\>` prompt. Built-in DOS commands
behave like the real thing; anything else you type is treated as a question and
answered by SERMO's conversational core.
A telnet server that drops every caller into a simulated **Margittai machine**
from the [Neumatronic universe](https://wiki.teletypegames.org/en/projects/neumatronic-universe/universe/alternative-history).
It runs a dual-architecture power-on, loads **SERMO** — *„a Szó"*, the Word —
and leaves you at a green-phosphor `> ` prompt.
SERMO is the canonical OS of the dual machine: a *single* prompt with *two*
destinations. A literal, exact command goes to the **digital** side (the first,
von Neumann architecture) and is served by built-in commands; anything typed in
**natural language** is treated as a question and routed over the **ADI-76**
bus to the **Lapis-ACP** (the second, analog-cognitive architecture) — SERMO's
conversational core. Black screen, green letters, one blinking line: exactly as
the canon describes it.
Built on the [rubbs](https://git.teletype.hu/tools/rubbs) gem, using its
configurable `BBS::FakeOS` character-mode OS simulator.

## Talking to SERMO / wiring an LLM
At the `C:\>` prompt, `VER`, `DATE`, `TIME`, `ECHO`, `MEM`, `DIR`, `CLS`,
`HELP` and `EXIT` are real commands. Type anything else and it goes to
`Sermo::Oracle.answer`, which currently returns canned, in-character replies.
At the `> ` prompt the **digital side** answers literal commands: `VER`,
`DATUM`, `IDO`, `MOND`, `MEM`, `KAT`, `ADI`, `VOX`, `CLS` and `KILEP` (English
aliases like `DATE`, `TIME`, `ECHO`, `DIR`, `EXIT` still work; `SUGO`/`HELP`/`?`
lists them). Type anything else and it crosses the ADI-76 bus to the
**Lapis-ACP** via `Sermo::Oracle.answer`, which currently returns canned,
in-character replies (its voice follows the canon — *ExistentialAI* and
*Nokia-punk*: a doubting, intimate machine, because there is no other interface).

A simulated OS is pure configuration: a `BBS::FakeOS.define { … }` block with a
`prompt`, `colors`, a `boot` sequence, a `command` table and an `on_unknown`
