V.42 is a transmission protocol with error detection. This powerful backup protocol works with a special Link Access Protocol for Modems (LAP M) based on the standardized HDLC protocol. V.42 implies the Microcom Networking Protocol (MNP 4) as a so-called secondary method for flow control between data terminal equipment (DTE) and modem (DCE). Two variants are provided: Hardware control via separate interface lines and software control XON/XOFF.
