Salut. 
Am observat urmatorul comportament bizar al driverului de port serial: din userspace scriu urmatorii octeti: 46 6C 6F 72 69 6E, se receptioneaza corect in kernel, se transmit tot acestia in rutina de tratare a intreruperii THREI, numai ca in rutina de tratare a RDAI receptionez urmatorii octeti: 6 C F 12 9 E
Cele doua porturi seriale au fost setate la fel.
Daca incerc sa afisez in userspace sirul citit se corupe display-ul (apar tot felul de caractere ciudate pe ecran).

Are cineva vreo idee? 
Multumesc
