在多台微机上频繁地安装大量的软件,耗时而又费力。下面介绍一种用数据传输的方法安装微机软件,简捷而又快速。 (1)无调制解调器双机通讯的硬件实现:“无调制解调器”(NULL-MOODEM)进行数据传递的方法是用电缆连接两台微机的串行口或并行口就可以完成把文件从一台微机传送到另一台微机。连接两台微机可以用9针或25针插头,要传输数据有3根线是必须的,它们是地对地、发送对接收、接收对发送。如果用户希望远程传输,则需要7根线,即另加上RTS对CTS,DSR对DTRCTS对RTS和DTR对DSR之间互联的4根线。
Frequent and laborious installation of large amounts of software on multiple computers. The following describes a method of data transmission using computer software installed, simple and fast. (1) without modem hardware implementation of dual-machine communication: “no modem” (NULL-MOODEM) data transfer method is to connect the two computers by cable serial port or parallel port to complete the transfer of files from a computer To another computer. Connect two computers can use 9-pin or 25-pin plug, to transmit data there are three lines is necessary, they are ground-to-ground, send to receive, receive to send. If the user wishes to transmit remotely, seven lines are required, plus four lines of RTS to CTS, DSR to DTRCTS to RTS and DTR to DSR.
