51接收字符串演示程序.rar

单片机可以接受超长字符串，当然字符串来自PC，其他的也可以，

收到后再原封不动的发回来，本代码12MHz,波特率为4800，有11.0592M的话可以更完美，（9600下可以误差0 ，当然的你自己去改本代码）

本代码现在可以在4800,12M下正确发送94个单字字符

（注：第64个支付被丢后面的前移一个字符，因为12M下波特率不是标准的4800）

或31个双字节字符（汉字）。-51 to receive the string demo program. Rar MCU can accept a long string, of course, the string from the PC, the other can also be received and then sent back intact, the code for the 12MHz, the baud rate to 4800, 11.0592M words can be more perfect, the error is 0　(9600 under, of course you change this code) of the code is now in 4800,12 M sent 94 word character (Note: 64 payment to be lost behind forward a character, because 12M baud rate instead of the standard 4800), or 31 double-byte characters (Chinese characters).
