The README says who wrote it and the two projects it was built for, WII6 and OGLAS, with their sites; credits Ground Control for the modem and the library that does the protocol work; and gives the licence with contact details, where to report issues and what helps in a report, and that it is not a Ground Control product. The licence, every source file and the Python package's metadata carry the copyright and email; the package lists its homepage, repository, issues and changelog.

Ground Control's RockBLOCK 9704 (Iridium Certus, IMT messages) on the

UART its devicetree node sits on. Builds Ground Control's library,
|
|
pinned pristine at modules/lib/rockblock9704, with a Zephyr serial
|
|
port and one worker thread that owns it. <rb9704/rb9704.h> is the API.

The modem takes up to 100 kB, and the library keeps one static buffer
|
|
of this size for messages out and one for messages in, plus one in
|

this module for the copy rb9704_send takes. 2 kB is three buffers of

2 kB; raise it as far as the RAM allows.

Measured, not guessed: the library parks a 1.5 kB MT segment on the
