| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 99 === RS-232 standard is usually used as serial communications interface between DTE (Data Terminal Equipment) and DCE (Data Communication Equipment) or peripherals.
However, limiteded by the electrical characteristics, RS-232 interface was defined as a kind of low speed communication interface, and was mostly used at the local end.
While most of the RS-232 applications in consumer electronics have been replaced by USB, RS-232 is still widely used and as a main communication interface in the industrial applications.
To overcome the limitation from RS-232 architecture, we propose the scheme that control the RS-232 COM Port from the remote side through Ethernet, and due to the fact that the Java SDK doesn’t support RS-232 anymore, we developed an scheme to support serial function in order to implement remote serial port control.
In our experiments, we deployed the scheme in Windows environment and properly set the parameters of remote RS-232 COM Port. We may, therefore, conclude that our approach is workable
