10.8.3.2 CommsMemFree(2)
CommsMemFree(2) displays the number of memory "chunks" in "keep" memory
(p. 519)
used by communications. It includes memory used for PakBus routing and
neighbor lists, communication timeout structures, and TCP/IP connection
structures. The PakBusNodes setting, which defaults to 50, is included in
