I'm unsure what you're asking here, Ian, but if you just wanted to plug an ADSL modem/router into a telephone connection over here, it wouldn't work as you need an appropriate broadband account (ManxNet, Domicilium, etc).

If you just want an ADSL connection to upload stuff, check emails etc, send me a PM and you can pop over here to my flat and connect in to my router assuming I'm not up on the mountain marshalling, naturally

Alternatively, if you're on wireless, I think that the Java Lounge cafe above the cheap bookshop near Cowley Groves, Chrystals etc estate agents in Douglas has free wi-fi assuming you're having a coffee
