If you transfer alot of GIFS and other compressed data, the MNP compression would just make everything take alot longer. I think that MNP5 would be a GOOD idea. Since you are going to be mainly going long distance, anything that could save some transmission time will save you money. MNP5 can give aprox %80 faster throughput on text-based transfers. On other transfers the throughput could be less, but would still provide some increase in throughput in most circumstances. The extra cost is usually only $50 or so more - well worth the investment. If the compression technique actually increases the transfer time, as it might in cases where the material being transfered is already compressed. If this is the case, you can turn off the MNP5 compression for the transfer, reversing (to the throughput of a normal 2400 bps modem) the throughput decrease. -Chris -- Chris Swanson, Chem/CS/Pre-med Undergrad, St. Olaf College, Northfield,MN 55057 DDN: [CDS6] INTERNET: swansonc@acc.stolaf.edu UUCP: swansonc@stolaf AT&T: Work: (507)-645-6845 Home: (507)-663-6424 I would deny this reality, but that wouldn't pay the bills...
