I did. Unfortunately nobody seemed particularly interested in implementing
all those wonderful features like modulo-128 packet numbering and packet
window negotiation.  Nor did Telenet seem interested in fixing their
switches to not act as though the D bit were always set.

Paper specs by themselves don't do much for me.

The more gratuitously complicated a protocol is, the greater the
opportunity for the vender to screw it up.
