From data flow diagram can be seen, if you are using data transmission characteristics of audio equipment, devices serial might receive unexpected unformatted data. Such as a serial port to send a query command, and hope to receive a query response, but may receive unformatted data. Devices serial is therefore required to deal with such exceptions

As can be seen from the data flow diagram, if you use the audio device data forwarding feature, devices serial may receive unexpected unformatted data. For example, the serial port of a query, the query expects to receive a response, but it is possible to receive unformatted data. Hence the need for such devices serial handling abnormal situations

From the data flow diagram can be seen, if the use of audio equipment transmitting characteristics of data, no devices data serial may get a surprise. For example, the serial port to send a query command, and expect to receive a query response, but may have no data format. So you need devices serial for this kind of abnormal processing
