new write block is sent back to the controller using the

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 ReadSwitches 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.
