EIA/TIA-232
Purpose: This section describes the physical layer in more detail.
Note: 802.3 is responsible for LANs based on the carrier sense multiple access collision detect (CSMA/CD) access methodology. Ethernet is an example of a CSMA/CD network.
EIA/TIA-232 and V.35 are physical standards that support synchronous serial.
