10.4.3.2 CommsMemFree(2)
CommsMemFree(2) displays the number of memory "chunks" in "keep" memory
(p. 457)
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
CommsMemFree(2). Doubling PakBusNodes to 100 doubles
CommsMemFree(2) from ≈300 to ≈600 (assuming a large PakBus network has
not been just discovered). The larger the discovered PakBus network, and the
larger the number of simultaneous TCP connections, the smaller
