SCON = 0x50; /* SCON: mode 1, 8-bit UART, enable rcvr */
TMOD |= 0x20; /* TMOD: timer 1, mode 2, 8-bit reload */
TH1 = 221; /* TH1: reload value for 1200 baud @ 16MHz */
TR1 = 1; /* TR1: timer 1 run */
TI = 1; /* TI: set TI to send first char of UART */
#endif

while (1) {
P1 ^= 0x01; /* Toggle P1.0 each time we print */
printf ("Hello World\n"); /* Print "Hello World" */
printf ("中文发送\n"); }
}
这是C51\EXAMPLES\HELLO项目中的文件。中文信息当做字符串可以发送。
超级终端再设好端口号，与单片机的串口正确连接后，就可以了。

超级终端，收到后，自然，就能显示出来对应的汉字。
