Abstract
A software asynchronous communication protocol between two computers allows the roles of master and slave to be switched between the computers, depending on the nature and direction of the communication. In order to avoid truncating bit strings transmitted between the computers due to a difference in the write/read cycles of the computers, the software incorporates a dwell to accommodate the slowest computer in the system.
