 The ITERM programme help contains the description of the programme main functions.
 At higher baud-rates, even if possible, it cannot be used to upgrade the OS304Plus CTD firmware.
Therefore, modify the OS304Plus communication speed and set it to the 9600bps value before
continuing/proceeding with the firmware upgrading.
 During the firmware upgrading, the Xon/Xoff RS232C protocol is used by the CTD to communicate with the
ITERM programme. Therefore, before proceeding, the Xon/Xoff must be enabled in the ITERM
programme by accessing the serial port set-up and enabling the "Software transmit" and "Software
receive".
