BTW I bought a UK 56k modem recently (Diamond Supra) and had to snip two
of the wires to get it to work; the symptom was that connecting the modem
cable to the modem and the wall socket killed dialtone, whether the modem
was on or not. Obviously bad.
Can't remember the wiring now though, sorry ;) A bit of trial and error
would sort it.
