‘I’ – 49h – Data IN to EEPROM (v4.20 and later)
The MiniTerm contains 256 bytes of user-definable EEPROM that may used to
store arbitrary data. Common uses include serial number information and
product key codes. The latter allows a programmer to enable some or all
aspects of an application, thus acting like a dongle or hardware key. The
programmer may use this space for any purpose.
The data in the user-definable area of EEPROM is byte-addressable and will
survive normal end-user operations such as CKD file downloading, two-finger
resets and even advanced mode programming. The only way to erase the data
is to overwrite it with new data using this command. The IN (write) command
format is:
@ I <address byte> <data byte>
Where:
@ is the command prefix.
I is the command.
Address byte is any value from 0 to 255 (decimal).
Data byte to write is any value from 0 to 255 (decimal).
Example: Write value 0x34 to location 0x56.
