ABSTRACT:
A dial-up asynchronous communication protocol allowing multiple POS terminals to efficiently multi-thread transactions to a host computer and to interleave mail messages and file transfers while retaining the ability to suspend these mail messages and file transfers when credit card authorization requests from the terminal or responses to those authorization requests from the host become available, and resume the mail messages and file transfers after the requests or responses have been transmitted.
