Follow guidance to migrate from pyserial to serialx - #95
No actionable comments were generated in the recent review.
Walkthrough
The package moves serial communication from pyserial to serialx. The Docker image installs serialx, connection setup and error handling use serialx APIs, and package metadata and the changelog identify version 1.4.0.
Changes: serialx Migration
Layer / File(s)
Summary
Dependency and release metadata tekmar_packetserv/Dockerfile, tekmar_packetserv/config.json, tekmar_packetserv/CHANGELOG.md
The Docker image installs serialx instead of py3-pyserial. The package version and changelog identify version 1.4.0.
Serial connection handling tekmar_packetserv/rootfs/usr/local/packetserv/packetserv.py
Serial connection modes use serialx.serial_for_url with the described port settings and explicitly open the selected port. Serial-thread, port-opening, and port-closing handlers also catch OSError.
The migration installs serialx and opens each configured connection before processing packets; no actionable merge-blocking risk was identified.

Explanation
The title states the main change: moving the integration from pyserial to serialx. The raw summary confirms the changes to packetserv.py, the Dockerfile, the version bump, and the changelog all implement this migration. The title says "Follow guidance" which names the reason, but the title is specific enough that a teammate scanning history understands the primary change.
Full details: Docstring Coverage
Explanation
Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 1 files.
Full details: Description check
Explanation
The description links the Home Assistant guidance on moving from pyserial to serialx and states the intent of the change. It does not include any of the template's review guidance items as checked-off content, and it does not describe the implementation details, testing performed, or confirm that the branch is up to date with upstream. The template is mainly a set of contributor guidelines rather than fill-in sections, so the description is brief but covers the purpose. The template also asks that testing be done against real Tekmar hardware through the 482 gateway, and the description does not state whether this was done.
Resolution
Add a short description of what changed in the code, such as the switch from the serial module to serialx, the new serial parameters (9600 baud, 8 data bits, no parity, one stop bit), and the added OSError handling. State whether the changes were tested with Tekmar hardware through the 482 gateway. Confirm the branch is based on the latest upstream main branch. Keep the change limited to the migration, and move any unrelated edits to a separate PR.
