 The configuration of the COM ports on each I-7523 module is
as follows:
Baud Rate
Parity
Data
Stop-bit
The InitHP() and CloseHP() functions of hp23_M.c are given as

follows:
void InitHP(int ComNo)
{
com[ComNo].ComNo = ComNo;
com[ComNo].BaudRate = 9600L;
com[ComNo].DataFormat = Data8bit + NonParity + Stop1bit;
com[ComNo].CheckSum = CHKSUMdisable;
