First, this is the wrong list for this question as it is concerned with kernel development, not application developement. Second, you must prevent the thread/process to get stuck in the first place. Depending on what the driver supports, you should try to open(2) the HDLC device with the O_NONBLOCK flag and modifiy the read/write handling according to non-blocking mode, or use a select(2) before every read/write to see if the actual call would block (and not call read/write in this case, of course).
