Specifies the amount of memory that the CR1000
allocates for maintaining PakBus routing
information. Represents roughly the maximum
number of PakBus nodes that the CR1000 is able to
track in its routing tables (see section

Keyboard: Status Table ≈ line 33
CRBasic: variable = status.keyword
Array indicating numbers of buffers used in
communications except with an external keyboard
display. Two digits per each buffer-size category.
Least significant digit specifies the number of the
smallest buffers. Most significant digit specifies the
number of the largest buffers. When TLS is not
active, there are four categories, "tiny", "little",
"medium", and "large". When TLS is active, there is
an additional fifth category, "huge", and there are
more buffers allocated for each category. See
section CommsMemFree(1)
(p. 491).
