OCXcip_WriteConnected
routine.
 display "open success" on the 4-character display using the function Display.
 read the state of the Setup Jumper using the function

and prints
this information to the console.
 If the block number is not the expected number, the 16-bit integers in the
write block are incremented to form a new write block of data which is sent to
the Controller using the
OCXcip_WriteConnected
API routine. The program
then waits for another block of data from the Controller using the
OCXcip_WaitForRxData routine.
 If any of the calls to an OCXcip library routine fail, the returned error code is
converted into a human readable string using the OCXcip_ErrorString routine
and printed to the console.
