Hello, I just assembled a mini IR receiver for the serial Port. This device shows the IR-code by pulling DCD up or down. As there is no software for FreeBSD supporting IR I would like to have a try and code it myself. Unfortunately those Pulses sent by the IR device sometimes only last a few milliseconds. Now my question: How can I sense the state of the DCD line that quick? I can meassure the overal time with gettimeofday() but how can I sense DCD?
