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).
