[GreenKeys] Model 15 without blank key

[steve bennett]

 Are there plans available to simulate the function of a blank key in machines that do not have one?I still don't know what it does but now I know it exists so I have to have one.Sounds like a worthy Arduino project.I apologize it is past my bed time and I should not be typing this late.
Cheers, -Steve

 The ASCII DEL (aka RUB OUT) would be equivalent (bit wise at least) to 
Baudot LTRS.  That is, all bits are set.  So, to correct a mistyped 
character on a tape, you mechanically back it up one space, punch LTRS 
or DEL, as appropriate, then type the correct character.

The blank key, IIRC, might do a control function such as motor start. 
ASCII has an equivalent all zeros character, NULL.
