First, let me apologize for mistyping NQC as NCQ. Hey Ben! Hope those rumors are true. So if they are going to do something with remote switches and such, will it be similar to DCC or radio/infrared control? I'm guessing some form of remote control. (...)

Thanks Dan.

(...) you never check if your speed is 0 in this task - IMO, you need to add: if (__speed == 0) {Off(OUT_A)}; (I'm guessing here, since I haven't really done any NCQ myself yet. :/ Dan (25 years ago, 22-Mar-00, to lugnet.robotics.rcx.nqc, lugnet.trains)
