Use QLocalSocket and optionally QSocketNotifier.

How about:

int fd = open("/dev/ttySAC0", O_RDONLY|O_NONBLOCK);
QSocketNotifier *socNotify = new QSocketNotifier(fd, QSocketNotifier::Read, this);
connect(socNotify, SIGNAL(activated(int)), this, SLOT(your_read_function(int)));

int fd = open("/dev/ttySAC0", O_RDONLY|O_NONBLOCK);
QSocketNotifier *socNotify = new QSocketNotifier(fd, QSocketNotifier::Read, this);
connect(socNotify, SIGNAL(activated(int)), this, SLOT(your_read_function(int)));

/dev/ttySAC0 is not a file, it's a stream you can connect to using QLocalSocket. Or you can use QSocketNotifier with native stream handling (see the example squidge gave you).
