Method cmdDrive

src/core/TciProtocol.cpp:543–558

DRIVE and TUNE_DRIVE are global commands per the TCI v2.0 spec — they have no TRX prefix. Spec form: `drive;` for GET, `drive:N;` for SET. The dispatcher's isSet heuristic (args.size() >= 2) is wrong for globals (treats `drive:50;` as a GET). We override here: any args at all = SET, no args = GET. We also accept the legacy TRX-prefixed form `drive:0,N;` for backward compatibility — when 2+ args ar

// for backward compatibility — when 2+ args arrive, we take args[1] as the
// value and ignore the trx index (drive is global anyway).

    if (args.isEmpty()) {
        int pwr = m_model ? m_model->transmitModel().rfPower() : 0;
