I've read some of the threads here. Here's what I've done:
Upgraded modem to V.90 using latest file.
Put in (and taken out)suggested (by Dell) init string
Unhooked everything! used direct line to phone line.
Reset dial-up adapter
All of these things were done as a Dr. would do a diagnosis, so the order here may be incorrect, but what I'm trying to say is 'been there, done that'. My older computer connects at least at 28.8. I never get more than 24000 bps on the new one. Please can someone help me?!! Thanx
