Accessing Remote System Resources in an OS/2 Environment

       Disclosed is an OS/2* application called the Device
Manager, which can grant local access, of system resources to
applications running on remote PCs.

      The Device Manager process has two functions:
           - provide low-level access to devices on a PC controller
           - execute/queue commands on a PC controller

      These functions are initiated via messages from other
processes.  For all devices on a controller the Device Manager gives
the capability to open, read, write, and close that device.  The
commands received are commands that could be executed by themselves,
however, the Device Manager allows multiple processes to submit these
same commands. The Device Manager will process the commands
sequentially as received.  If there is already a command being
executed when a new command is received, that new command will be
queued for later execution.  Device Manager is responsible for the
execution of commands that allow the submitting processes to
continue, without having to wait until the desired command completes.
An important concept of the Device Manager is that there exists one
Device Manager per controller (PC). Any of the resources available on
a single controller are now available to any process in the system
that has been configured to communicate with the specific Device
Manager. Hence, some processes can be configured to support all of
the available...
