Features
- Custom serial-device assignment — RS-232 instruments become first-class. Instruments the Lager Box cannot identify by USB enumeration (first case: the Rigol DP711 power supply, reached through a generic Prolific USB-serial cable that enumerates as the cable, not the PSU) can now be assigned to their cable once with
lager nets assign. From then on the instrument scans, nets, and drives exactly like an auto-detected device. lager nets assign—--listshows assignable devices, current assignments, and unassigned USB-serial cables;lager nets assign Rigol_DP711 --serial <USB_SERIAL>(or--port <sysfs-path>for serial-less clone cables) stores the assignment on the Lager Box, durable across reboots and replugs.--baudoverrides the catalog default when the instrument’s front panel differs;--as-net [NAME]creates the net in the same step;--removeunassigns.- Assign Device flow in the Net Manager TUI — the interactive twin of
nets assign: pick a cable, pick the instrument (with optional baud override), and name its net in a follow-up dialog. Assignments can be removed from the same screen. - Rigol DP711 (DP700-series) support — single-channel RS-232 power supply driver with the DP800-compatible method surface, addressed by a durable
serial://<vid>:<pid>/serial/<s>(or/port/<p>) identity that re-resolves to the live tty at open time — surviving tty renumbering, port moves, and replugs — with stale-session self-healing. - Generic
POST /net/commandendpoint on the Lager Box HTTP server for Tier-1 instruments (GPIO, ADC, DAC, thermocouple, watt-meter, e-load), giving them the same warm in-process path the supply/battery endpoints use instead of a subprocess per call. ThenetCommandcapability is advertised in/statusonly when the route actually registers.
Improvements
- Nets live and die with their assignment. Removing (or replacing) a cable assignment deletes the saved nets bound to its address and reports them; pre-existing generic-UART nets on the cable are retired at assign time so a terminal session can never fight the instrument driver for one tty. A baud-only re-assign keeps existing nets.
- The scanner reports assigned instruments, not their cables.
lager instruments, the TUI, and the Lager Box’s/instruments/listshow the catalog instrument at its durableserial://address; the cable’s generic UART record is suppressed while assigned, and assigned ttys are excluded from the Dexarm G-code handshake probe. - Backend JSON parsing is robust to doubled output for objects, not just arrays — both the CLI and TUI parsers now take the first complete JSON value, fixing a latent recovery bug for the known “double execution” Lager Box output.
Bug Fixes
- Manually-added supply and battery nets are driveable again.
lager nets add/delete/add-batchnow normalize the legacy role tokenssupply→power-supplyandbatt→battery; the short tokens were previously saved verbatim, producing nets that listed fine but that no supply/battery command could drive. The tokens remain accepted as input aliases,deletereaches legacy nets saved under either spelling, and channel validation for supplies now actually runs onnets add. - Documentation and error hints no longer reference the nonexistent
lager nets createfamily — renamed to the realadd/add-all/add-batchcommands across the docs, READMEs, and four runtime error messages, and the documented role vocabulary now matches what saved nets actually carry. - The DP700 driver reports a missing cable as a device-not-found error when unplugged mid-session, instead of a raw Python traceback.
