I was beginning to think I needed some way to wait on the USB/Com Port, but wasn't sure how to do that.
This works great. My code change ..
void ComPort::ReadComPortDataMsg(char *data)
{
    int cnt = 0;
    int received;
    char c;

    data[0] = 0x00;
    do
    {
        received = read(hComPort, &c, 1);
        if ((received == 1) && (c >= 0x20) && (c <= 0x7E))
        {
            data[cnt++] = c;
        }
        else if (received < 0)
        {
            
        }
    } while ((c != dlim) && (cnt < 255));
    data[cnt++] = '\0';
}


Not sure how to deal with received < 0. Do you know where can I read up on
struct termios
and
global errno variable
?
Thanks!!!
