Abstract: A multiplexing non-device specific stream module is provided to an operating system. The multiplexing non-device specific stream module includes a number of upper and lower ports. Each port, lower as well as upper, has a write queue, a read queue, and an associated control and status data area. Additionally, the multiplexing non-device specific stream module further includes a number of service routines, in particular, a splice/unsplice routine, a change ownership routine, and a query ownership routine. Together, these elements cooperate to allow multiplexing of connections to input/output devices with improved performance and flexibility, while maintaining compatibility.
