No, it's not an internal winmodem, it's a regular cable modem. I would imagine that a linux dialer program could do it. I did not know about the aformentioned kppp, and I'll look into it. As for Guillermo's suggestion about checking half/ full duplex on the modem, I see nothing of the sort in the modem's control panel. So I don't know one way or the other. In any case, the computer and modem in question are in Haifa and because of the current situation we are not returning there for at least a few more days. Good thing that I backed up the previous night and I have all my files, email, etc on disk with me here. When I return I'll look into kppp and see where that leads me. Thanks.
