NxConsole is a related feature based on an NxTerm.  It takes I/O from /dev/console so provides an NSH shell on a framebuffer.

There are several screenshots of an NxConsole (running under the NxWM window manager) here: https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=139629473&preview=/139629402/140774634/NxWM-ScreenShots.pdf

Sounds like you need an nxterm.  An nxterm is the logical counterpart to an xterm.  You can find it at nutts/grapphics/nxterm.

It supports echoing text in a framebuffer and quite a few VT100 keyboard inputs.  There are all also lots of example to illustrate building and using it.  It hasn't been used in a long time so I can't guarantee its current state.

There is a lot of discussion in Confluence as well.  This is probably to the point: https://cwiki.apache.org/confluence/display/NUTTX/NxTerm+Example
