1、用RS－232C的零MODEM的连接法连好两机的连线；
2、用DEBUG的O命令将一数发送到串行口(2F8H/3F8H)，然后在另一台机上用 I命令读入串行口的内容。如果发送的的内容与接受的内容一直，说明两机已经连好线，否则必须检查连线，直到两机可通讯为止；
3、编一程序，将一台机的键盘输入的键值通过RS-232C口送到另一台机，并在CRT上显示键值；
4、编一程序，通过RS-232C口进行一台机到另一台机的文件复制。
-1, with RS-232C connection zero MODEM law even better connect the two machines 2, with the O command DEBUG a few sent to the serial port (2F8H/3F8H), and then on another machine with I command read the contents of the serial port. If you send the content and the content has been accepted that two planes have been even better line, he must check the connection, until the two planes may be far communications 3, made a procedure will be a machine keyboard keys through the RS-232C port to another machine, and key in the CRT display 4, made a program, through the RS-232C port for a machine to another machine to copy documents.
