Simple sample of using ReadWithTimeout on the NetBurner to read X bytes without any additional delays.

Read.cpp

void Read(int port, int messageLength, int timeoutTicks)
{
    const int MAX_DATA = 1024;
    if (messageLength > MAX_DATA)
    {
        cout << "This demo only supports lengths up to" << MAX_DATA<<'\n';
        return;
    }
    char read_buffer[MAX_DATA];
    int read_status = 0;
    int bytes_read = read_status;
    while (bytes_read < messageLength)
    {
        read_status = ReadWithTimeout(port, &read_buffer[bytes_read], MAX_DATA - bytes_read, timeoutTicks);
        if (read_status <= 0)
        {
            if (read_status < 0)
            {
                cout << "\n!!Error trying read from serial port: " << read_status << "!!!\n";
                return;

        bytes_read += read_status;

    }
    //do something with read_buffer - no guarantee it ends with \0 if it filled the entire buffer
    if (bytes_read < MAX_DATA)
