Thanks for testing.

Ok, unfortunate. I added this for detecting when a device disappears
(e.g. USB devices). I'd like to know what happens on MacOS X there. Do
you happen to have a USB-Serial device which you could unplug while
minicom listens on this device? (I guess a recent Mac won't have a
serial port so a USB-Serial device isn't that unlikely).
As a workaround you can change the return !ioctl(fd, TCGETS, &t); to
return 1;
