A data communication system and method for transmitting serial data, includes a transmitter for transmitting a fixed-length block of information, and a receiver for receiving the fixed-length block from the transmitter. The fixed-length block includes a plurality of sub-blocks, and the plurality of sub-blocks each have a variable length depending upon the data. When an amount of transmission data has a size less than that of the fixed-length data block at a transmitter side, the information is repeatedly arranged within a same block in a range not exceeding the block size so as to form the block. Thus, in the data communication system having a fixed-length data block, the unused portion of the fixed-length block is effectively utilized in a highly reliable data communication. If the data transmitted has a size less than that of the data area of the fixed-length data block, multiple sub-blocks and an error check code are stored within the data area. With such an arrangement, error-free data is preferentially received so as to improve reliability and data transmission efficiency.
