I've found some very strange problem. I've embedded device with linux (kernel 2.6.14 at the moment) and sometimes, after unexpected power failure, serial port stops receiving data. I can send data over the port, but can't receive (just nothing arrives). If, in such case, I will restart computer everything comes back to work. It happends for different types of serial ports (there are two standard ports on board, and 8 additional ports on advantech cards). How can I find where is the problem ? best regards Jarek.
