Martin's question is not nonsensical, and I imagine he understands the applicable networking concepts. His goal is to replicate the original dialup user experience and add a useful modern component - it's hard to justify keeping large machinery around if it's only there to look at. By adding the

Silvertel makes POTS line interfaces (SLICs) that work on 3.3v or 5v supplies. They do all the high voltage generation and impedance wizardry on the POTS side, then expose audio in/out and simple control lines. To complete the picture you'd have to generate the tones and decode the numbers but

Would this be a good job for the Viking Electronics DLE-300? It emulates a CO with a pair of POTS lines, so you can call from port to port on it. It emulates all of the correct tones and CPC, both modems think they are on POTS lines. Makes it very easy to connect a pair of modems back-to-back,

Re: Google, Wikipedia directly on ASCII terminal?

The tightwad fix is to bodge a PP3 battery onto a line splitter, which is often enough to convince modems that there is a phone line. There is no dial tone nor ring signal, so you need to turn off dial tone detection on the calling modem ("ATX1", IIRC) and somehow tell the answering computer to
