    Here's a link to the Google translated version of that article:

    The firmware supports "96 ASCII characters" but the description doesn't mention underline capability. There's no standard ASCII character to enable or disable underline; this is done through control characters or escape sequences such as ANSI, or one of the older terminal emulation standards such as VT-102. You need to use one of these schemes so whatever is sending the text to the AVR can tell it to turn underline ON and OFF.

    Then you would have to modify the firmware in the AVR to support those control codes, and to generate underlines on the characters that are flagged as underlined. Assuming the code actually generates the video signal directly, it may not have enough spare processing power to deal with underline.
