        I'm sorry but this advice should soon or already be obsolete. We have V90,
anybody buying a 56K modem should get a V90, unless their ISP still hasn't
got it, in which case I recommend changing ISPs. It is very unfortunate that
ISPs are taking so long to switch, it holds the market back and cases even
more market confusion than there already is. TTYL
