As I said, check with your provider. Chances are, your system is not yet
upgraded. VBE is one of the first. In fact, there will be support for 2x
as well on this system in the near future. I know I had problems with
one of my numbers until I adjusted this. Maybe you won't. The main
reason I provided this info was to alert you all to an upcoming trend.
One thing is for sure, it seems that you are going to have to buy a
modem that complies with your provider's equipment if you want to have
56K, at least at first. Most of the time 56K will be sold as a premium
service for a couple of bucks a month. Also, as I reported in an article
a little while back, some providers will no longer support 14,4.
I would like to hear from other people who have 56k. Has there been any
improvement in performance?
