! <p>This is a simple example reading FLASH. The result is shown above. At first
! there is a sequence of “R” and “S”. “S”
! means one packet is sent, and “R” means one packet is received. At
! the end, statistics are printed. “<span class=SpellE><span class=GramE>msgSent</span></span>”
! is the total number of messages sent, “<span class=SpellE>msgRcvd</span>”
! is the total number of messages received, and “<span class=SpellE>successRate</span>”
! is the raw success rate provided by the low layer. “Ni” is the time
! taken to gather network information, which is used to tune parameters. “Td”
! is the time taken to transfer the entire data once. “Rd” is the
! time taken to fill holes (to retransmit missing packets). And “total”
! is the total time taken (sum of the previous three).</p>

! <p>This is a simple example reading RAM. The result is shown above. At first
! there is a sequence of “R” and “S”. “S”
! means one packet is sent, and “R” means one packet is received. At
! the end, statistics are printed. “<span class=SpellE><span class=GramE>msgSent</span></span>”
! is the total number of messages sent, “<span class=SpellE>msgRcvd</span>”
! is the total number of messages received, and “<span class=SpellE>successRate</span>”
! is the raw success rate provided by the low layer. “Ni” is the time
! taken to gather network information, which is used to tune parameters.
! “Td” is the time taken to transfer the entire data once.
! “Rd” is the time taken to fill holes (to retransmit missing
! packets). “<span class=SpellE>Ec</span>” is the time taken to check
! whether there is an error in the data. Finally “total” is the total
! time taken (sum of the previous four).</p>
