ABSTRACT:
A method and system for interrupt-responsive execution of a communications protocol which obtains data sent by a sending computer a receiving computer via a communications interface. An interrupt handler routine is provided which includes the communications protocol. When data requested by an application executing on the receiving computer is received by the communications interface, an interrupt is sent by the communications interface to the CPU in the receiving computer. When this interrupt is received, the interrupt handler routine is immediately accessed and executed to timely execute the communications protocol. As a result, the communications protocol obtains the data from the communications interface before it can be overwritten by new data sent by the sending computer. The application program can then be executed at a later time to read the data obtained.
