I have a Supra 33.6 external modem that I use with the mini dock to get on the internet with the duo. Some times I have problems with the duo seeing the modem, the modem works good even tested it on my powerbook 160 and Mac SE and it worked fine. I tried the printer port but no luck. one question what is the modem used as the internal modem in the Duo 280c? I would like to try it, the Duo works fine it has a 1gig hard drive installed a IBM I think, so I would hate to see it go down starting with the serial ports. -- Your favorite stores, helpful shopping tools and great gift ideas.
