创建接收数据的缓存，并返回是否创建成功
Create a cache that receives data and return whether the creation is successful

将多个数据报文按顺序发到设备，并从设备接收返回的数据内容，然后拼接成一个Byte[]信息，需要重写UnpackResponseContent(Byte, Byte)方法才能返回正确的结果。
Send multiple data packets to the device in sequence, and receive the returned data content from the device, and then splicing them into a Byte[] message, you need to rewrite UnpackResponseContent(Byte, Byte) method to return the correct result.

读取流中的数据到缓存区，读取的长度需要按照实际的情况来判断
Read the data in the stream to the buffer area. The length of the read needs to be determined according to the actual situation.

接收固定长度的字节数组，允许指定超时时间，默认为60秒，当length大于0时，接收固定长度的数据内容，当length小于0时，buffer长度的缓存数据
Receiving a fixed-length byte array, allowing a specified timeout time. The default is 60 seconds. When length is greater than 0, fixed-length data content is received. When length is less than 0, random data information of a length not greater than 2048 is received.
