    Hi, I faced this problem where i wasn't able to connect to GPRS on Win2K/98 but was able to do so for WinXP. Somehow, I narrowed it down to the DSR line used in data communications. For your info, my modem wasnt using DSR (left floating).

    It works properly when I tied this line to ground or HIGH. When it was left floating, i probed this line at the end of the cable at the computer's side and found a 100mV p-p Saw-like waveform on the line.

    For another cable which worked on all three, I found a 30mV p-p similar waveform. Just wondering whether Win2k/98 are sensitive to DSR line? Thanks.

    Not that I am aware of, but with windows 98, I'd double check the drivers for the NIC card if thats what it is attached to, if its on USB, same thing, just make sure your PC is updated.
