![[Examples of application field]
Remote device control/monitoring of remote equipment using cellular phone packet communication terminals (e.g., vehicle position data management, remote equipment malfunctions diagnostics, etc.)
Security service (e.g., visitor/trespasser information conveyed to cellular phones, etc.)
Centralized equipment management in buildings and factories (e.g., management of air conditioning, lighting, various sensors, etc.)

Network software library - Ultracompact TCP/IP protocol stack (for 16-bit microcontrollers) [standard version]
M3S-T2-Tiny (hereafter abbreviated T2) is the communication protocol software library which just requires small memory. It achieves a very compact program size by keeping the number of functions to a bare minimum. It also supports the H8/300H and M16C series of 16-bit microcontrollers. For details, please see "Operating environment". This product provides the basic TCP/IP functions necessary for building network environments. (See the conceptual image shown below.)
