A different modem worked on both lines. Turns out the mysterious modem used the black/yellow leads for some kind of "data mode" switch. The telco installer had left the spade lugs loose inside the box and they had shorted together (as I recall). The other modem didnt even have the black/yellow conductors in the cable. kurt horton pur-ee!uiucdcs!horton
