There may be few of them, but one is very essential.
When there is no equivalent of TIOCMIWAIT available in your os, it will
be very hard to convert the code.

TIOCMIWAIT is the ioctl that returns precisely at the moment when a
handshake line (passed as a parameter) changes state.  This is
functionality you cannot simply emulate by calling some other ioctls.
