Appendix B. Status Table and Settings Table 121. Status-Table Fields and Descriptions Fieldname Description Variable Type MemoryFree Bytes of unallocated memory on the CPU (SRAM). All free memory may not be available for data tables. As memory is allocated and freed, holes of unallocated memory, which are unusable for final storage, may be created. Integer CPUDriveFree Bytes remaining on the CPU: drive. This drive resides in the serial FLASH and is always present. CRBasicC programs are normally stored here. Integer USRDriveFree Bytes remaining on the USR: drive. USR: drive is usercreated and normally used to store .jpg and other files. Integer CommsMemFree(1) See CommsMemFree(1) (p. 432). Number of buffers used in all communication, except with the 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 4 categories, "tiny", "little", "medium", and "large". When TLS is active, there is an additional 5th category, "huge", and there are more buffers allocated for each category. Integer array CommsMemFree(2) See CommsMemFree(2) (p. 433). Number of buffers remaining for routing and neighbor lists. Each route or neighbor requires 1 buffer. Integer array CommsMemFree(3) See CommsMemFree(3) (p. 434). Three two-digit fields, from right (least significant) to left (most significant): "little" IP packets available, "big" IP packets, and received IP packets in a receive queue that have not yet been processed. Integer array Default Range Edit? Info Type 4 kB and higher Status TLS Not Active: tiny: 05 little: 15 medium: 25 large: 15 huge: 0 TLS Active: tiny: 160 little: 99 medium: 99 large: 30 huge: 02 Mem Status At start up, with no TCP/IP communication : 1530 (30 little and 15 big IP packets are available. Nothing in the receive queue.) 531
