When the variable bSend is set to TRUE, the function F10_BKMV copies the characters of
the string sSendData to the buffer awSendBuffer beginning at awSendBuffer[1].
Then, F159_MTRN sends the data from the first element of the send buffer
(awSendBuffer[0]) as specified by s_Start. The length of the string to be sent (8 bytes) is set
at n_Number (using the function LEN to calculate the number of bytes). The data is output
from COM port 1 as specified by d_Port.
