Is there ANYTHING I can use old dial up modems for (other then dialing up the internet)?

Any old, or unique ideas on what I can do with them?  I have one that is fairly fast (an old cable modem) one that is medium fast (an old DSL modem) and one 56k plain vanilla dial up.

Most obviously, AWESOME project enclosures! Gut them and take advantage of all the engineered openings and light apertures. Instead of buying one of those chintzy HDPE project boxes and hacking out power supply openings and trying to align holes for LEDs, use the ones already there! The kind engineers of USR have already done the dirty work for you!

Thank you. I will keep that in mind also.

I keep a 56K fax modem around for sending and receiving faxes.

I was thinking about that too, If one has DSL, do they still need a fax modem though?

If they want to send and receive faxes from their computer rather than using a service. I use to have DSL and I would have my phone line go to a splitter one side going into my DSL Modem and the other side going into a filter going into my modem for faxes. Worked great.

It took me awhile, but I think I know what you mean now -- -- Thanks !

Packet radio, for one. For the the dial ups, anyway. A normal dialup modem isn't optimized for radio, but it can work (slowly).

Cable modems can sometimes be hacked--not in an "underhanded" way (such as to get free internet). Rather to explore, modify and use the built-in web server / DHCP server, etc.

Might take some serious hacking, it it's not a well-documented modem.

One possible hack would be connecting the modem to a microcontroller and accessing the internet, for instance.

(I have a DIGI portserver someone sent me, which is essentially an ethernet <-> RS-232 connection.)

I was wondering if it could be modified for short haul, like from room to room periphrial support.
.  You can do that with telephone modems, but a null modem cable works better. You can use a null modem cable, but Ethernet is faster. Most computers have E'net built-in, but, if you need a card, they can be found for < $20.

Well, I suppose it is "instructions" then, or at least, being pointed in the right direction for the proper instructions, since I am working blind on this one.

I mean, I have a tiny inkling of how the whole ethernet thing works where I am employed, but that is a bit more "over the top" then I need.
