Just a guess, since I don't generally use my ftdi chips this way (but have
used real serial ports this way), but termios has other members.  I'm not
entirely sure what the termios() function does (constructor of some sort?),
but you might try a memset(&options, 0, sizeof(options)); before you start
fiddling with them, or, better yet, a tcgetattr() first.  I have no idea if
tcflush() can fail, but you might also printf its return value.
