AT modem
A Hayes modem via the ACIA 6551 at $0380 (PicoWiFiModemUSB, real or emulated). ATZ then ATDT host:port — the server is chosen from the menu. The only connection method.

OricTel
Minitel 1B — Oric 1 / Atmos
A full Minitel 1B terminal for the Oric 1 and Atmos, connecting to Minitel servers still online.
Teletel/Antiope Videotex decoder, HIRES 40×25 rendering, G0/G1/G2 character sets, connection via AT modem (PicoWiFiModemUSB / LOCI) or a WebSocket bridge. Written in C and 6502 assembly (cc65). EUPL 1.2 license.
Features
What OricTel does
Full Videotex decoder
Teletel/Antiope protocol (STUM 1B): state machine for ESC, CSI (with parameters), US, SS2, REP, SEP, PRO1/2/3. Complete attributes (colour, flash, inverse, underline, conceal, double size).
HIRES 40×25 rendering
An assembly span engine (~300 cycles/cell), “dirty”-cell refresh, adaptive budget (keyboard always responsive). Hybrid colour heuristic via the Oric's serial attributes.
Connect to Minitel servers
AT (Hayes) modem via PicoWiFiModemUSB / LOCI — ATZ then ATDT host:port — or a WebSocket bridge. Predefined servers (PAVI 3617, MiniPavi) or free entry.
G0/G1/G2 character sets
G0 (alphanumeric + accents), G1 (2×3 mosaics, precomputed cache), G2 (extended CEPT, precomposed accents). Faithful rendering of Minitel semigraphics.
Minitel keyboard
All function keys (SEND, INDEX, BACK, NEXT, REPEAT, GUIDE, CANCEL, CORRECTION, CONNECT/END) mapped to CTRL+letter (Oric-1 & Atmos) or FUNCT+letter (Atmos).
Free (EUPL 1.2)
Released under the EUPL 1.2 license on GitHub. Runs on the Phosphoric emulator or on a real Oric fitted with a LOCI + PicoWiFiModemUSB.
Connection
Two ways to connect
WebSocket
A Python bridge (orictel_bridge.py) relaying TCP (port 3615) to a WebSocket Minitel server (ws://3617.fr/ws).
Via bridge
PAVI 3617
pavi.3617.fr:3617 — Teletel home page, the recommended server.
Server
MiniPavi
go.minipavi.fr:516 — a multi-service gateway. Free entry available for any other server.

Roadmap
Where development stands
OricTel is under active development (version 0.3.5), with a test suite (Videotex, ACIA/SMC, AT modem, keyboard, bridge) and decoder fuzzing. Indicative status below — the repository is authoritative.
