This paper discusses the principle and procedure of remote data communication by controlling modem-with directly programming, and introduces the process for achieving the remote and real time data transmission-with the help of TSR technique.

• 通过对调制解调器的直接编程控制，实现远程数据通信的原理、方法以及如何借助内存驻留技术实现数据的远程实时传送。
