Deuce didn't like the font and video/emu mode state information tacked onto

the DA response, so I added 2 new requests: CSI=1n and CSI=2n which query
a state report from the terminal (for font state or video/emu mode), the same
information returned in the DA in the previous rev, but in a format more in
line with the corresponding CSI? N h/l requests (no bit checking required).
