How small is "really small"? IBM made a terminal with a 5" screen for

And the Atari Portfolio runs a version of DR-DOS.
And the Poqet ran MS-DOS.

Both have serial ports available.
Both will run DOS software, including most of the undocumented calls, such 
as TSRs.
Either can function as a terminal.
