一个计算机网络要实现与异种网络或异种计算机的数据通讯,需要使用复杂而昂贵的网关(GATEWAY)。本文介绍的终端仿真技术,能经济、有效地进行异种计算机之间的数据通讯。我们用IBM-PC/XT微型机仿真宝钢冷轧厂西门子R30小型机的6329C打印机,从而实现了R30向PC机的数据传送。
A computer network Data communications with heterogeneous networks or heterogeneous computers requires the use of sophisticated and costly gateways (GATEWAY). This article describes the terminal emulation technology, economic and effective data communication between heterogeneous computers. We used the IBM-PC / XT microcomputer to simulate the 6329C printer of the Baosteel cold-rolling mill Siemens R30 minicomputer to enable the data transfer from the R30 to the PC.
