Editing Parallel Line Internet Protocol (section)

==Similar methods==
An analogous feature for serial communications ports is the [[Serial Line Internet Protocol]] (SLIP), using null-modem cables but allows the transfer of four bits at a time rather than one. It generally works at higher [[bitrate]]s. The method is based on the "Crynwr" standard devised by [[Russ Nelson]].

Ethernet may also be used as a direct computer-to-computer communications method using an [[Ethernet crossover cable]].

Other [[Point-to-point link|point-to-point]] connections, such as [[USB]] host-to-host bridges or cables, are also used to transfer files between two computers where a network is not necessary or available.
