Description: 单片机RS232/RS485串行发送实验（双机通讯）。
实验步骤：
（1），准备两台598K实验机，确定1号机为发送，2号机为接收；
（2），当作RS232接口实验时，1号机和2号机的P3.0和P3.1交叉相连，且两机共地；
（3），当作RS485接口实验时，1号机和2号机的A、B作对应连接，同时1,2号机的R/TEN接P1.0, P3.0接R0, P3.1接DI。
（4），先运行2号机，键入[27]-->[EV]使2号机处于接收状态P。，后运行1号机[26]-->[EV]使1号机处于发送状态,P。会闪烁，在1号机键盘上按动数字键，在2号机的数码管上应显示对应的数字键值。-Send Singlechip RS232/RS485 serial experiment (two-plane communications). Experimental steps: (1), prepare two sets of experiments 598K machine, determined on the 1st machine to send, on the 2nd machine to receive (2), as a RS232 interface experiment, on the 1st and the 2nd machine and P3.0 P3.1 cross-linked, and the two planes were to (3), as a RS485 interface experiment, on the 1st and the 2nd machine A, B for the corresponding connection, while 1,2 No. of R/TEN then P1 .0, P3.0 access R0, P3.1 then DI. (4), first run on the 2nd machine, type [27]
