There was one problem - there's no phone socket anywhere near my desk, and no extension cord long enough to reach the nearest one. But fortunately the phone line actually enters the flat right here, so I just wired the modem directly into the junction box. I expect that's hopelessly illegal, but it seems to be working fine.
From the repetitive-sounding module news department, I've released yet another new version of PadWalker (0.08) which fixes even more bugs and also adds a secret hook into the internals for Richard Clamp to use in his nefarious activities. Peter Scott has submitted his debugger patch which relies on this new version.
