可供使用的函数名:
char getbyte(void) 从接收缓冲区取一个byte,如不想等待则在调用前检测inbufsign是否为1。
getline(char idata *line, unsigned char n) 获取一行数据回车结束，必须定义最大输入字符数
putbyte(char c) 放入一个字节到发送缓冲区
putbytes(unsigned char *outplace,j) 放一串数据到发送缓冲区，自定义长度
putstring(unsigned char code *puts) 发送一个定义在程序存储区的字符串到串口
puthex(unsigned char c) 发送一个字节的hex码，分成两个字节发。
putchar(uchar c,uchar j) 输出一个无符号字符数的十进制表示，必须标示小数点的位置,自动删除前面无用的零
putint(uint ui,uchar j) 输出一个无符号整型数的十进制表示，必须标示小数点的位置,自动删除前面无用的零
delay(unsigned char d) 延时n x 100ns
