这家伙很懒，什么也没写！

问题已经解决:在telnet数据反馈添加格式符号处理，遍历所有将要输出的数据BUF，取出每一条完整的字符串分别发送出去。
具体代码实现如下：
```c
rt_uint8_t *send_ptr = RT_NULL;
                rt_uint8_t *send_ptr_t = RT_NULL;
                rt_uint8_t *send_ptr_t2 = RT_NULL;
                rt_base_t level = rt_hw_interrupt_disable();
                int send_len = rt_ringbuffer_peak(telnet.tx_rb, &send_ptr);
                rt_hw_interrupt_enable(level);

if(send_len > 0)
                {
                    send_ptr_t = send_ptr;
                    send_ptr_t2 = send_ptr;
                    m = 0;
                    for(i = 0; i < send_len; i++)
                    {
                        if(*send_ptr_t == '\n'){
                            memset(readbuf,'\0',512);
                            memcpy(readbuf, send_ptr_t2 + m, (i+1) - m);

if(readbuf[0] == '\n')
                            {
                                ;
                            }
                            else if(readbuf[6] == '\n')
                            {
                                send(telnet.client_fd, readbuf, 6, 0);
                            }
                            else {
                                readbuf[(i+1) - m] = '\r';
                                readbuf[(i+2) - m] = '\n';
                                send(telnet.client_fd, readbuf, (i+2) - m, 0);
                            }
                            m = i + 1;
                        }
                        else if(*send_ptr_t == '\b')
                        {
                            memset(readbuf,'\0',512);
                            memcpy(readbuf, send_ptr_t2 + m, (i+1) - m);
                            readbuf[(i+1) - m] = '\r';
                            send(telnet.client_fd, readbuf, (i+2) - m, 0);
                            m = i + 1;
                        }
                        send_ptr_t++;
                    }
                    client_tick_timeout = rt_tick_get() + rt_tick_from_millisecond(telnet.client_timeout * 60000);
                }
