First I plugged a multimeter to check the range of the signal and not fry anything. Then I used a DS0138 oscilloscope to monitor the signal and to guess voltages and baudrate (a resistor divider is suggested in order to lower the voltage). Later, an 8-channel USB logic analyzer (4-5 USD) can be used to capture data into the computer. **REMEMBER** to convert voltages to 0-3.3v before connecting it to logic analyzer or you will make magic smoke. You can use the read circuit below.
