Fred:
The big office supply chains (Staples, Office Depot and similar) still sell 
honext-to-goodness real 56K serial modems -- usually Zoom. I suspect that 
they are sold to low traffic SOHO market for FAX and answering machine 
service. Back in my DOS days, I used a PCTools program that served as a phone 
directory, dialer and call logger. Very convenient. Hmmm...
