The Smallest Communication Program in the World?

  cmp  ax,2E00h              ; ALT-C
  je   pregetstatus
  cmp  ax,2D00h

I only know a little assembly (just learning it for the past couple weeks), but couldn't he do a byte comparison and save a byte for each of these comparisons in his immediate data? Like so?

  cmp  ah,2Eh              ; ALT-C
  je   pregetstatus
  cmp  ah,2Dh

I'm making the assumption that a key press will fit in a single byte... I'm not sure this is true.

It could have even been smaller if he'd left out the 'clear screen' functionality ;-)
