Now, fd is just a file descriptor of the device which is used to the serial communication. The

variable phaseTableLen keeps the value taken from t

visible on the picture 6.6-1, and it decides how long our phase tables should be. Next variables

ph1, ph2 and ph3 are just pointers to generated phase tables. The variable working is used to

check whether we are doing now some detection or not. The function initport

makes

initialization of the serial port according to the given parameters. The functions writeport

and

readport

are used to respectively send and get some message to/from the serial port. The

function getbaud

reads the baud rate used in the transmission. The function allocateMemory,

as it names states, allocates memory for phase tables. The deallocateMemory makes opposite to

previous function. It releases allocated memory for phase tables. The functions openDevice and

closeDevice respectively open and cl ose serial port for communication. The next one is:

generatePhaseTable and it only generates phase tables exactly in the same manner as

pxmc_init_ptable_sin3phup described in subsection: 5.3.12. The last function: detection(…) is

used to call command processor directive: detection, and then to work in proper manner with

results which it returns.
