Well we could report the instance: eg. 1 for tty1, 2 for tty2, that could
be useful and wouldn't waste too many bytes...

Keyboard Status Report (Source: VT420 Progamming Summary, p147):

  Request (Host to VT420)   CSI ? 26 n
  Report  (VT420 to Host)   CSI ? 27 ; Pla ; Pst ; Ptyp n

     Pla = keyboard dialect
       1 = North American
       2 = British
       3 = Flemish
       4 = French Canadian
       5 = Danish
       6 = Finnish
       7 = German
       8 = Dutch 
       9 = Italian
      10 = Swiss French
      11 = Swiss German
      12 = Swedish
      13 = Norwegian
      14 = French/Belgian
      15 = Spanish
      16 = Portuguese
      28 = Canadian (English)

     Pst = keyboard status
       0 = keyboard ready
       3 = no keyboard
       8 = keyboard busy

     Ptyp= keyboard type
       0 = LK201
       1 = LK401

DECREPTPARM (Source: http://www.cs.utk.edu/~shuford/terminal/virek100.txt)

   Report  (VT100 to Host)   CSI Ps ; Pp ; Pb ; Px ; Pr ; Pm ; Pf x

      Ps = type of report
       1 = report as requested by the host
       2 = unsolicited report

      Pp = parity
       1 = no parity
       4 = even parity
       5 = odd parity

      Pb = bits per character
       1 = 8 bits
       2 = 7 bits

      Px = transmit speed
      Pr = receive speed
       0 =    50 bps
       8 =    75 bps
      16 =   110 bps
      24 =   134.5 bps
      32 =   150 bps
      40 =   200 bps
      48 =   300 bps
      56 =   600 bps
      64 =  1200 bps
      72 =  1800 bps
      80 =  2000 bps
      88 =  2400 bps
      96 =  3600 bps
     104 =  4800 bps
     112 =  9600 bps
     120 = 19200 bps

      Pm = bit rate multiplier
       1 = 16x

      Pf = value of the for switches in block 5 of SETUP-B if the STP
           option is installed.
