*
* In addition to the individual control of the communication
* channels, there are a few functions that globally affect the
* communication processor.
*
* Buffer descriptors must be allocated from the dual ported memory
* space. The allocator for that is here. When the communication
* process is reset, we reclaim the memory available. There is
* currently no deallocator for this memory.
* The amount of space available is platform dependent. On the
* MBX, the EPPC software loads additional microcode into the
* communication processor, and uses some of the DP ram for this
* purpose. Current, the first 512 bytes and the last 256 bytes of
* memory are used. Right now I am conservative and only use the
* memory that can never be used for microcode. If there are
* applications that require more DP ram, we can expand the boundaries
* but then we have to be careful of any downloaded microcode.
*
