The present invention relates to a method in connection with serial data, to recognize a frame synchronization pattern, and for the sake of providing a fast and reliable search algorithm especially for V.110 synchronization pattern, the present invention suggests a method characterized by examining two successive bytes by performing a binary AND operation between the first byte and a check byte made up from the value of the second byte, examining if the AND operation is zero for thereby establishing whether said first byte and second byte qualify as candidates for the synchronization pattern, and further verifying said candidates by checking further criteria given by the frame in question.
