+ read(int &len) -> read(int max_len)
+ add EspiaDev &m_dev as a private member of EspiaSerialLine class
+ move the serial line code from EspiaDev to EspiaSerialLine
+ change #define TMOUT to an enum inside of the class
+ m_line_term to be a string not char
+ get/set m_timeout, m_line_term - setTimeout, setLineTerm (virtual)
+ read() is blocking, while readAvail() is non-blocking; add max_len to
 readAvail() and remove the timeout (set it to TMOUT_NO_BLOCK internaly)
+ default timeout in read? yes, but we need to state the meaning of -2 clearly.
  or no timeout in the methods at all, use only m_timeout? no.
+ flush() can read bigger chunks, or right on the number of available bytes
+ remove block_size and block_delay as a parameters of the methods, add them
  as a private variables (with get/set functions) and use them instead
+ group default parameters at the end
