My colleague and I believe your absolutetly correct!!!!!!!!
We can't believe we missed that, timing issue!!!!!

Your right about the 2 bits missing in my equation (Start & Stop bit),  your
also right about
immediately after my write I jump into my read.  By the time I initiate my
write and actual bits
start pumping out, I am already started in my read routine counting down
time.  Not only that,
but it takes time for the embeded unit to process that byte determine what
it needs to do with it
and then dishout a response, which then it has to be placed in the uart of
the pc, then go thru
who knows how many Window layers, before it actually gets placed in the que!

I will take a good look at what you told me to try, but I believe that by
just incrementing my
millisecond multiplier it will take care of the issue I am seeing.

Here is my init function of the port by the way:

/---------------------------------------------------------------------------
---
//   Initialize and configure the port
//--------------------------------------------------------------------------
----

bool __fastcall Comm::PortInitialize(char *COMSEL)
{
 // Local variable declarations
 DCB  dcbPort;        // Structure for a serial communications device.
 bool bRespond;       // Signals if the COMM tested, is free

   // Open the serial COMM port
   hComm = CreateFile (COMSEL,                        // Port name
                       GENERIC_READ | GENERIC_WRITE,  // Access (read/write)
                                                      // mode
                        0,              // Share mode(object cannot be
share)
                        NULL,           // No security attribute
                        OPEN_EXISTING,  // How to open the serial port
                        FILE_FLAG_OVERLAPPED, // File attributes
                        NULL            // hTemplate is NULL for comm
devices
                       );

    // Check if the commport is free
    if (hComm == INVALID_HANDLE_VALUE)
     bRespond = false;

    else
     { // Begin else statement (comm is free)

       dcbPort.DCBlength = sizeof (DCB);

       // Get the default port setting information
       if (!GetCommState (hComm, &dcbPort))
        // Report the error
        ReportError();
       else
        { // Begin else statement (GetCommState)

          // Change the DCB structure settings
          dcbPort.BaudRate = 9600;        // Current baud
          dcbPort.ByteSize = 8;           // Number of bytes
          dcbPort.Parity = NOPARITY;      // Parity
          dcbPort.StopBits = ONESTOPBIT;  // Stop bit

          // Configure the port according to the specifications of the DCB
          // structure
          if (!SetCommState (hComm, &dcbPort))
           bRespond = false;
          else
           { // Begin else statement

             // The next three lines tell the read function to return
             // immediately when no bytes are waiting in the port's receive
             // queue
             memset(&comtime, 0, sizeof(comtime));
             comtime.ReadIntervalTimeout = MAXDWORD;
             SetCommTimeouts(hComm, &comtime);
             // Port available
             bRespond = true;
           } // End else statement

        } // End else statement (GetCommState)

     } // End else statement (comm is free)

   return bRespond;
}

I probably will not respond until tomorrow, since I am going to go ahead and
test, everything out!

Thank you,
