Hi,
But xport from lantronix is not a dialup device, its ethernet based. I would need a PPP serial connection to the ISP, like it is in a standard modem internet connection, where the operating system (Windows) manages all of the protocols tcp/ip and ppp and the user does not have to bother with all of the details. I would like to have a integrated circuit which does this.The Seiko s7600a did exactly that, but they stopped the production??!!??Who knows why?!
Regards.
