Describe the bug
linux receive miss 0x11 0x13 0x0d

Desktop (please complete the following information):

• OS: [e.g. DeepIn 15.11 64bit
• Compiler: QT 5.12.6 GCC 6.3.0
• Version: 4.0.2.200108

• solution ：
  because termios not set c_iflag

c_iflag &= ~( ICRNL | IXON);

0x11 VSTART(crtl-Q, ^Q)
0x13 VSTOP(crtl-S, ^S)

ICRNL 将输入的回车转化成换行 (0x0d => 0x0a)
IXON 允许输出时对XON/XOFF流进行控制 (0x11 0x13)

recommend set

term.c_cflag |= CLOCAL | CREAD;
term.c_lflag &= ~(ICANON | ECHO | ECHOE | ISIG);
term.c_oflag &= ~OPOST;
term.c_iflag &= ~(BRKINT | ICRNL | INPCK | ISTRIP | IXON);
