I have a jaton wincomm 56 modem, with a cirrus logic chipset. As of late I have been having all kinds of problems with my computer, and have fixed them, but the only one that I haven't figured out is this one. I am occasionally (like twice today so far) getting a blue screen on my computer when I am on the internet. It directs me to the clmport and an address having a problem with clmport and another address. I thought it was the drivers, but have downloaded the latest version from jaton, and am still having the same problem. the blue screen does let me recover, and I am able to disconnect and reconnect the modem, but it is annoying.... any suggestions???(am using win98, and my other problems were coming from the bus speed on my board.... didn't like 75)
