FIELD: communication.
SUBSTANCE: invention relates to network communication technologies. Disclosed is method of serial interface in bus system containing two bus subscribers, exchanging messages by bus, wherein sent messages have logic structure corresponding to ISO 11898-1 standard for CAN protocol, said logical structure includes frame starting bit, arbitration field, control field, data field, cyclic redundancy code (CRC), acknowledgement field and sequence end frame, control field includes data length code containing information on data field length, characterised by that in presence of first mark (EDL) control field in messages comprises, in contrast to ISO 11898-1 standard for CAN protocol, more than six bits, wherein first mark (EDL) is implemented by recessive bit in control field, and in presence of first mark after recessive bit of first mark (EDL) in all information messages should be at least one dominant bit (r0, r1).
EFFECT: technical result consists in improvement of data transmission speed.
