@Quietman posted:While fairly well known ion the other scales, both MTH and Lionel's tendency to keep their coding "secret" to a certain extent has prevented it making in roads into DCS and Legacy / TMCC. Yet many DCC system manufacturers have given JMRI the info to interface with their hardware. There may be a reason that it hasn't penetrated the O-scale market, but Lionel's protocol specification ain't it.
Well, to be 100% correct, Lionel has released both the TMCC protocol specification long ago, and the Legacy protocol specification a few years ago. MTH never released the DCS protocol specification. Let's not paint them all with the same brush.
