You have a multiconductor cable; while it's intended for PS/2, if it has at least three conductors (which I believe PS/2 does), it can be used perfectly well as a serial line. You'll need adaptors on the ends of the cable, but they need be only passive adaptors. RS-232 is ridiculously tolerant of layer-1 issues. Unless the insulation is rated for only 6V or something, which strikes me as unlikely enough that I wouldn't even bother checking if it were me in that situation. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
