/*!
* \brief
* Send a command to modem and check if the response matches to
* \c expected. If so read any token inside response marked with
* \c Marker, convert the value into type \c T and write it to \c t
*
* \param cmd The comand to send (null terminated)
* \param expected The expected response
* \param t The value to return
* \param timeout The timeout in CPU time (leave it for 0 - no timeout)
*
* \tparam T The type of the value to read from response marked with \c Marker
* \tparam Marker The marker character
* \return True on success
*
* example
* \code
* BG95<256> modem;
* std::thread th1 ([&](){
* modem.inetd(false);
* });
* int status;
* bool done = modem.command("AT+CREG?\r\n", "\r\n+CREG: 0,%\r\n\r\nOK\r\n", status);
* if (done && status == 1)
* std::cout << "Connected to home network\n"
