| Abstract: | The hardware platform was designed which takes ARM920T-cored $3C2440A as the master control- ler and employs DM9000AEP Ethernet controller chip; the Linux operating system being applicable to the em- bedded serial port server system was built and transplanted, and though making use of the perfected TCP/IP protocol, the multi-threaded web server program for ARM side was designed. The two-way data transmission realized between RS-232 serial port and Ethernet data can allow the existing intelligent Ethernet to access the Ethernet successfully. |
