Hi Peter,
that is the same as in the standard serial.pp:
Result := fpopen(DeviceName, O_RDWR or O_NOCTTY);
and this fpopen will block as long as minicom is not started on that
device.
Try to add O_NONBLOCK to the flags with fpopen. Then set CLOCAL like
Peter suggested. Then disable O_NONBLOCK again with fcntl if you want
blocking I/O back.
