FYI, I received the following from Zonet:
Our ZCF5610 has no driver support for PocketPC 2003 at its current stage. An update driver patch is in the process of developing and the estimated release time is November 03. The beta version will post on our website,
www.zonetusa.com, for customer to download.
I received this modem last week. I am anxiously awaiting this new driver. It isn't a flip-up modem so I hope that I can connect at various speeds successfully.
Have a great day!
