Device-Independent Support in Communication Environments

       A mechanism is disclosed for supporting various
communication devices using a common set of Application Programming
Interface calls.  The mechanism provides for an object-code
compatibility of applications across a variety of hardware devices.
Additionally, this mechanism has been implemented for asynchronous
communications.

      The mechanism is illustrated in the figure, and is explained
more concisely in terms of the implementation. Bindings between
devices, device drivers and connection subsystems can be made at
system configuration.  Common application communication verbs are
mapped within the "Communications Subsystem" into device specific
actions (commands and signals), and the device responses are also
mapped into given application verb return messages.
