When a slave device is addressed by the master:
1) In case of reading request of the value contained in a window, the
slave answers a string equal to the one sent by the master but in

0x02
0x80 (for RS 232 and RS 422 only)
0x80 + device number (0...31)
0xFF: brodcasting command (recognized by all the
devices, it doesn't implicate any answer)
(for RS 485 only)
window depends to the device type
alphanumeric ASCII string containing, in the case of
writing operation,the parameter to input into the

may have variable length according to the data type
contained in the window where you are working in. In

doesn't exist.
