Re: Some modems dont work on some lines

I can recall an instance where a modem worked on one phone line but not
another.  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.
