My first ever modem was the Zoom 2949L and I was wondering if I could, with the help of an Arduino, somehow "simulate" traffic and make the lights blink like they used to 
I see here that you can make it work without a telephone line, so I would just need to send analog data somehow over the phone jack and receive it on the serial port.
How complicated is this, and can an Arduino help?
Thanks for any help!

That link uses 2 modems.
Trying to use arduino for this would be a formidable task if at all possible.
There are some providers though that still offer dial up services.
Calling one of them could get your lights flashing.
If all you need to do is get lights flashing you can use arduino to talk to the Modem's serial port with an RS-232 voltage conversion and Software Serial.. You can make a tone generator (maybe even Arduino can) to produce the 1070-1270 Hz ones of a telephone line system.
Look a the modem specs. What tone pairs does it say it can use??
Another option is to gut the modem and install an Arduino with several LEDs to do the simulation; various random blink codes, etc.

May be possible to generate the tones but there is still the handshaking to take care of.
Early modems used FSK.
His employs QAM but it may me backwards compatible.

Probably he easiest idea
Thanks for the replies - I wouldn't want to gut it, since I'm not that good with soldering, but I see that it's not as simple as I thought.
Hi,
See THIS about an Arduino MODEM..
