‘F’ – 46h – Show Firmware Version on the LCD (v4.20 and later)
If you would like to present the user with the firmware version string it can be
done using this command. The version string is 16 characters long and will
appear at the current cursor position.
The F command is similar to the ^F command (06h) except that the latter
command sends the string to the host.
This command does not reset the keypad but it should be noted that using the ^D
(04h) command will reset the keypad and thus show the version string as well.

The LCD might show (depending on the LCD size and cursor position):
MiniTerm – v4.20
FEh – LCD Compatibility Mode Prefix (v4.20 and later)
This command does NOT require the @ prefix byte.
Its purpose is to allow
backward compatibility with the vast amount of existing Serial-LCD
software packages (E.g. LCD Smartie HD44780S.DLL).
After the MiniTerm receives the 0xFE byte, the next byte will be sent directly to
the LCD control register. This allows the programmer direct access to the LCD
without using the Genovation command set. This also maps the 8 user-defined
(custom) LCD characters to the legacy positions (in decimal) 176, 158, 131, 132,
133, 134, 135 and 136 as well as preferred locations 0x18 through 0x1F.
Example: Clear the LCD using direct access.
