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.
