The networking of passive serial device means, all devices in the system are passive to
wait for a connecting,only the background server sponsores the networking and does
request or data download. Typical applications are such as some wireless sensor network,
each sensor terminals always are doing the real-time data collection, and the data
collected does not immediately upload, but temporarily stores in the devices. The
background servers periodically connect devices actively, and request to upload or
download data. At this time, background server works as a TCP Client, while the device
works as a TCP Server.
