GAO's V.42 software is designed for optimum asynchronous-to-synchronous conversion as well as error detection and retransmission of damaged data. The ITU-T V.42 standard addresses two major problems for asynchronous devices: an asynchronous-to-synchronous conversion protocol and a sophisticated error-detection process for asynchronous systems. This recommendation contains an HDLC-based protocol referred to as the Link Access Procedure for Modems (LAPM).
