shown in Figure 4-1, you will get the log output described below:
tx_contin_en 1: continuous Tx mode with a duty ratio of 100%
tx_contin_en 0: Tx packet mode
tx_cbw40m_en 0: 11n HT20, 20M bandwidth
tx_cbw40m_en 1: 11n HT40, 40M bandwidth
3. Click on "stop" to end the Tx process and the returned message is "cmdstop".
