/**
* @brief wait for signals with parameters.
*
* for multiple devices test cases, DUT might need to wait for other DUTs before continue testing.
* As all DUTs are independent, need user (or test script) interaction to make test synchronized.
*
* Here we provide signal functions for this.
* For example, we're testing GPIO, DUT1 has one pin connect to with DUT2.
* DUT2 will output high level and then DUT1 will read input.
* DUT1 should call `unity_wait_for_signal("output high level");` before it reads input.
* DUT2 should call `unity_send_signal("output high level");` after it finished setting output high level.
* According to the console logs:
*
* DUT1 console:
*
* ```
* Waiting for signal: [output high level]!
* Please press "Enter" key to once any board send this signal.
* ```
*
* DUT2 console:
*
* ```
* Send signal: [output high level]!
* ```
*
* Then we press Enter key on DUT1's console, DUT1 starts to read input and then test success.
*
* Another example, we have 2 DUTs in multiple devices test, and DUT1 need to get DUT2's mac address to perform BT connection.
* DUT1 should call `unity_wait_for_signal_param("dut2 mac address", mac, 19);` to wait for DUT2's mac address.
* DUT2 should call `unity_send_signal_param("dut2 mac address", "10:20:30:40:50:60");` to send to DUT1 its mac address.
* According to the console logs:
*
* DUT1 console:
*
* ```
* Waiting for signal: [dut2 mac address]!
* Please input parameter value from any board send this signal and press "Enter" key.
* ```
*
* DUT2 console:
*
* ```
* Send signal: [dut2 mac address][10:20:30:40:50:60]!
