Damn, damn, damn! Today I went to work and left my modem switched on and the home PC connected up — it was synchronising the latest bunch of photo files. I got home to find that the synchronisation hadn’t completed because it had been disconnected. Unfortunately my home PC is configured to dial-on-demand (something I’ve never got to the bottom of and disabled). The PC dialled up the modem bank, the modem bank answered, then failed to authenticate the connection, so it hung up.
