If it is true, is there any way Yes this is true. There are a couple of ways to get around it. I'm familiar with pckwik & pc-cache & both systems allow you to turn caching off and on from the command line. Another solution is that both allow you to specify the maximum block size to be transfered to the disk. This sets the maximum time the interrupts will be disabled. Pckwik, at least, has a discussion of this in their manual. The pc-cache manual discusses the disabling of interrupts but doesn't specifically relate it to communications programs. Hope this helps, Ken
