Abstract
A master-slave switch method for reversing roles between nodes in a network environment when the traditional role reversal functionality as defined by the network specification is not implemented within the node is presented. A data terminal which does not support the traditional master-slave switch functionality, progresses as far as establishing an asynchronous connectionless (ACL) connection. The LAN access point then request a role switch, when the reversal of roles fails, the connection is aborted with device addresses of the participating entities being stored. The LAN access point then initiates the reestablishment of the connection in a master role with the data terminal assuming a slave role after verification of the device address of the LAN access point.
