With this option enabled the user can speed up adding a large amount of data to the stream buffer
by minimizing the usage of the nxscope lock interface:
nxscope_lock(&nxs->nxs);
nxscope_put_vfloat(&nxs, 0, data0, 1);
nxscope_put_vfloat(&nxs, 1, data1, 1);
nxscope_put_vfloat(&nxs, 2, data2, 1);
nxscope_put_vfloat(&nxs, 3, data3, 1);
nxscope_unlock(&nxs->nxs);
If the code only change c_oflag, c_iflag and c_lflag, not c_cflag in termios.
