I do experience serious problem with interrupt driven serial communication. I am using Dzcom0.99i library, and from time to time I can send nothing via my serial port. After successfull initialization(dzcom_init and comm_port_init) I send bytes to port via comm_port_out function. I see that they are witten into queue, but they are not sent via serial port. I checked this using terminall program on other computer. I think, I have problem with interrupt. I must add that this happend from time to time ( not always , more or less 3 times from 10) right after initalization. If datas are transmitted successfully via com after initialization, I experience no problems till program termination. I am also using allegro timer interrupts in my program. Cound it be that this is the reason? Please, help me if you can Artur Pendzich
