This doesn't have all the info you would like, but I'm at work (???) and 
the modem info is at home.  Practical Peripherals (if they're still in 
business) has a 2400 EFMX modem that worked pretty well, for 2400 line 
speed-it would accept 9.6 dte speed.  The downside is that it was ac 
powered (transformer & 110VAC) but when I was playing with it, it 
handled inbound calls from cell phones to a cell phone and regular line.
The other company was Paradyne (AT&T).  I ordered 4 of the pcmcia and 4 
of the desktop.  The desktops arrived after I quit the company, but I 
was told the desktops worked fine.  I have one of the pcmcia in my pc 
and haven't had any real bad experiences; a couple of dropped calls that 
when the bill came, the call was credited as a dropped call.  My 
sessions usually aren't more than 3 minutes.  I don't recall the model 
number for the Paradyne, but AT&T change their model numbers with the 
weather, it seems...a call would give you the latest and greatest.
