It sounds like the *coiling* of the telephone cord is the most likely
culprit. Considering the length from home to central office, I really
don't think that shortening the length from wall jack to modem, per se,
helped matters. I *do* know that automobile ignition wires have a cross-
induction problem when you run them side-by-side for long distances, and if
a data communication path is marginal anyway (as this one sounds), any
"signal-shaping" modifications (like a coil to cut high frequencies??)
would likely only hurt matters.
On the other hand, I'd still be surprised to find that coiling the phone
cord could make any noticeable difference in signal quality.
