Using templates instead of bridge pattern in C++

I have three types of data link: RS485, I2C and Bluetooth. Every data link have functions like connect, read and write data. On PC software I must implement application/protocols layers to work with devices. In my previous question about OOP I got the answers to use Bridge pattern or factory method but I think this can be done better. I would ask if is not better to use templates to this task. Here is my simple example how I want to use it:

// Low level datalink class
class RS485
{
public:
    void send(const char *data) {
        // datalink function to send data
        printf("RS485: %s \n", data);
    }
};

class I2C
{
public:
    void send(const char *data) {
        // datalink function to send data
        printf("I2C: %s \n", data);
    }
};

class BT
{
public:
    void send(const char *data) {
        // datalink function to send data
        printf("BT %s \n", data);
    }
};

// Protocol class
template<typename Comm>
class MODBUS
{
public:
    MODBUS(Comm *c) { _c = c; }

    void send(const char *data) {
        printf("MODBUS\n");
        _c->send(data);
    }
private:
    Comm *_c;
};

// Protocol class
template<typename Comm>
class TCP
{
public:
    TCP(Comm *c) { _c = c; }

    void send(const char *data) {
        printf("TCP\n");
        _c->send(data);
    }
private:
    Comm *_c;
};

int main() {
    // Modbus over I2C
    I2C *i2c = new I2C();
    MODBUS<I2C> *mb_i2c = new MODBUS<I2C>(i2c);
    mb_i2c->send("Data ...");

    // Modbus over RS485
    RS485 *rs = new RS485();
    MODBUS<RS485> *mb_rs = new MODBUS<RS485>(rs);
    mb_rs->send("Data ...");

    // Tcp over Modbus over RS485
    TCP< MODBUS<RS485> > *tcp_modbus_rs = new TCP< MODBUS<RS485> >(mb_rs);
    tcp_modbus_rs->send("Data ...");

    return 0;
}
