Worse, that reported number is just the driver's guess at the reported speed. some old OS 9 modem files simply reported everything at a single speed. And then there was "Modem Magic", which was purported to be special high-speed modem scripts for the Classic OS. All they did was set the modem string to AT&F8 which was standard AT 'run with all your fast doo-dads enabled' default command, then published a totally bogus number. I can, with ten seconds time in bbedit, convince OS 9 that your 56K modem is actually working at 98K. All it is is changing one text string. Of course it was largely a placebo effect, except for modems that didn't properly register the AT extended commands used in classic modem scripts, people expected faster connections, so they got 'em, especially if the they paid $49.95 for them... Modems vary greatly in their ability to handle line noise, etc. If you're using a modem, make sure all your connections are good,and that you're using a good phone line. One that's been walked on or cat- chewed for years probably won't sustain a higher speed connection. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
