چکیده
Industrial appliances do usually have RS232 ports to enable computer control and monitoring. In this paper we present a system to allow remote control by GSM/GPRS messaging not disturbing local link. To do so, the module must include a port arbiter to handle bi-directional communications between a RS232 and the two other ports (RS232 and GSM/GPRS).

Dual-port serial arbiter with GSM modules for simultaneous local/remote control of RS232- based devices
Home and industrial appliances do usually have RS232 ports to enable computer control. In this paper we present a module to both extend the serial communications port for other devices or protocol adapters and to allow remote control by SMS messaging. To do so, the module must include a port arbiter to handle bi-directional communications between a RS232 and the two other ports (RS232 and GSM).
