How else does one use their dial-up modem?
One phracks an audio signal with a switch box tone producer that can create standard DTMF, quarter insert tones, and an audio based modem? Granted, you'd need a pay phone for that. The other option if you do have a pay phone in an out of the way place is to look for a square box with a screw on lid a few feet down the cables coming from the phone. If you get that lid off, you should have a jack that the linesmen use to test, but is also perfectly compatible with a standard rj11 phone cable to your modem.
