Bug? Imodem feature? Have you received a reply yet? I am experiencing the same problem on 2.2.1-RELEASE and 2.2.2-RELEASE. My symptoms are varied. For 2.2.1-RELEASE, I rarely get the hang, but it does happen. For 2.2.2-RELEASE, I get the hang almost immediately upon talking to the modem with the GENERIC kernel. When I added the plug-and-play patches, it did not change the characteristics of the behavior, but if I remove the plug-and-play soundcard, the likelihood of the hang, decreases significantly (it will EVENTUALLY hang, but it takes a much longer session). I was also under the impression that using a faster sio speed (115200 versus 38400 or 57600) will decrease the likelihood, but I do not have enough data points to substantiate that. On precisely the same system (with and without the soundcard), I have zero problems with Win95, so it is highly unlikely that the problem is with the hardware.
