Summary
HDMI matrix switcher supporting 4K HDR video routing. Control via TCP/IP (Telnet daemon on port 23, HTTP on port 80) and RS-232 (configurable via CSpara command). Commands are case-sensitive, terminated with CR (0x0d); feedback terminated with CR+LF (0x0a). Login mode disabled by default; no password required unless IPLogin is enabled.

Notes
- Commands are case-sensitive and must be entered as documented.
- Each command terminated with CR (0x0d); feedback terminated with CR+LF (0x0a).
- If command fails or entered incorrectly, feedback is "Command FAILED".
- Telnet daemon enabled/disabled via
Telnetcommand; HTTP daemon always available on port 80 (per System feedback). - IPLogin disabled by default — no username/password required to control over TCP/IP unless explicitly enabled.
- Internal EDID slots 1-14 described in EDIDMSet command documentation.
- Broadcast mode allows concurrent routing of one input to multiple outputs.
- Save/Recall presets 1-8 for I/O route settings.
- Firmware version retrievable via
VersionMCU; model name viaType; system info viaSystem sta. - Port 23 (Telnet) and port 80 (HTTP) observed in System feedback; IPPort command can change TCP control port.
- CSpara status query
CSpara[sta]returns current serial config; source example echoesCSpara [115200,8,0,1], taken as the default serial configuration (115200 8N1).
Upgrade done. Changes vs on-disk:
- Added `command:` payload (verbatim) to all 38 actions — main fix (implementability rule).
- Populated serial defaults (115200 / 8 / none / 1) from `CSpara[sta]` feedback example; flow_control stays UNRESOLVED.
- Fixed `output_status` enum `[sta]` → `[on, of, sta]` (was incomplete; source line 504).
- Bumped `created_at` to today; all IDs/shapes preserved.
