Abstract
Short Message Service (SMS) in GSM system is designed to provide a vehicle for delivering length-limited data messages between subscribers. The paper describes a prototype system that is capable of providing a Short Message Command Interface (SMCI) for subscribers using GSM-enabled terminal devices to access remote PCs or workstations by DOS or Unix commands. This prototype system is composed of three parts: the SMCI Clients, the SMCI Server, and the SMCI Gateway. The SMCI Clients can send commands to the server (and get results from the server) via the SMCI Gateway. By taking advantage of this prototype system, we can login remote machines and can access value-added services provided on those machines
