Description
These support random and sequential mass storage devices, sockets, serial ports etc. They can be called from any active CDL object that has a reference connection to them, but since they can block outside of CDL for indeterminate periods, are usually accessed by threads rather than methods.
Devices are referenced through access functions whose names are derived from device instance names.
