I think RHIDE still has source code available, even if it's 23 years since the last update? Real problem with implementing such a terminal-mode GUI is that Unix/Linux terminals clung to a terminal standard which didn't provide all the features of an MS-DOS text mode program. In particular, it can't recognize the Alt key by itself, or Alt+Letter key combinations. Or Ctrl+Shift+Left/Right keys.
