"""V1 (legacy) Omni-Link protocol over UDP.

The v2 path in :mod:`omni_pca` (TCP, OmniLink2Message, StartChar 0x21,
parameterised RequestProperties / RequestExtendedStatus) is what most
modern firmware speaks. This subpackage exists because some panels are
configured at the network module to listen on **UDP only**, in which case
PC Access falls back to the v1 wire protocol (typed RequestZoneStatus,
RequestUnitStatus, etc., StartChar 0x5A, OmniLinkMessage outer = 0x10).

Reference: clsOmniLinkConnection.cs:353-360 (ConnectionProtocol() returns
V1 for Modem/UDP/Serial, V2 only for TCP).
