I have seen smart telco simulators for $250-$500 (Software Results made
the "COMBOX(R)" for about $350) and I have seen dumb ones for <$100. The
dumb ones are a power supply, some current-limiting resistors, and a push-
button to switch 110VAC through some other resistors and simulate the
ring voltage. I do not have a schematic, but I've seen someone sell them
at hamfests for cheap.
Most expedient is if you have two phone lines. Next most expedient is if you
live close enough to a friendly neighbor to run a wire out the window. :-)

I picked up a
TI Silent 700 model 707 recently (a nice, small variant
with built-in modem, see http://pobox.com/~fmw/misc/Silent700.jpg),
with hopes of converting to use as a direct line serial terminal.
Before I open it up and poke around, does anyone already know how to
do this?
Oops, wake up.
Yes, get a telco simulator (costly) and a stand alone modem
(cheap, esp. when used). The sim I found was a Viking at about
$100, useful for testing laptops with integrated modems, etc. etc.
Or get two phone lines and call yourself.
Terminal/w/Modem -> Telco(sim) -> Modem -> RS232 out.
