3、1)数据报以一个称作END（0xc0）的特殊字符结束。同时，为了防止数据报到来之前的线路噪声被当成数据报内容，大多数实现在数据报的开始处也传一个END字符（如果有线路噪声，那么END字符将结束这份错误的报文。这样当前的报文得以正确地传输，而前一个错误报文交给上层后，会发现其内容毫无意义而被丢弃）。2)如果报文中某个字符为END，那么就要连续传输两个字节0xdb和0xdc来取代它。0xdb这个特殊字符被称作SLIP的ESC字符，但是它的值与ASCII码的ESC字符（0x1b）不同。3)如果报文中某个字符为SLIP的ESC字符，那么就要连续传输两个字节0xdb和0xdd来取代它。图2-2中的例子就

4、是含有一个END字符和一个ESC字符的IP报文。在这个例子中，在串行线路上传输的总字节数是原报文长度再加4个字节。2命令集索引CMDCOMMENTDATAACKDATA0xE500FPGA image downimage0x5E00Ack status0xE501DSP bootloader downimage0x5E01Ack status0xE502FPGA bootBoard num0x5E02Ack status0xE503DSP bootBoard +dsp number0x5E03Ack status0xE504Set serial port baudPort +Baud rate
