Laplink (sometimes styled LapLink) was a proprietary piece of software developed by Mark Eppley and sold by Traveling Software.[1] First available in 1983,[1] LapLink was used to synchronize, copy, or move, files between two PCs, in an era before local area networks, using the parallel port and a LapLink cable or serial port and a null modem cable or USB and a USB adhoc network cable.[2][3][4]
Traveling Software is now known as LapLink Software, Inc.,[5] and their main software is now the PCmover. With the demise of parallel ports on PCs Laplink no longer sells the traditional cable. Instead it has USB to hard drive, USB to USB and Ethernet to Ethernet cables.[6]
