pretty much OT: acoustic coupling

my application anyway. What is the typical maximum speed of such a device, be it antiquated (I actually used to have one of the old Radio Shack units), or home-brewed. And lookee, here's what I had: http://cgi.ebay.com/RADIO-SHACK-ACOUSTIC-COUPLER-MODEM- TRS-80-AC-3_W0QQitemZ180098721480QQcategoryZ80229QQss PageNameZWDVWQQrdZ1QQcmdZViewItem In fact, that's an acoustic modem. What I'd like to implement is a "bridge" if you will between a modem and a cellular device that would allow connection to the internet. Ingenious, no? ;) Please, no one tell me about software and such that's presently available on the market. I'm aware of it, own 99% of it, and I'll say here and now it's flakey at best. The technology is antiquated enough, albeit not the application. O woe is me :( ____________________________________________________________________________________ We won't tell.
