SerialPort.cpp:801:15: warning: this 'if' clause does not guard... [-Wmisleading-indentation]
               if (m_modemState == STATE_IDLE || m_modemState == STATE_POCSAG)
               ^~
SerialPort.cpp:803:17: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the 'if'
                 err = pocsagTX.writeData(m_buffer + 3U, m_len - 3U);
                 ^~~

and
