Abstract: The article puts forward a new way of high transmission velocity and better reliability of serial communication between computer and multi-singlechip system.Based on the 32 bit Windows environment,multithreading technology is adopted so as to realize serial communications real time character.Slow-moving character and uncertainty character in traditional serial communication are solved effectively.A new real-time and long-distance communication means between epigyny computer and 196-series multi-singlechip system is put forwarded.It is realized with RS-485 bus way.A full communication protocols and relevant software and hardware realization are presented.
