Other than using EMM/QEMM and the devicehigh and loadhigh commands to make sure that drivers get loaded into "upper" ram (unused areas betweem 640k and the 1 meg limit, there's not much you can do if the programs aren't written to use it. Desqview or Taskmgr effectively create separate "640k" (minus drivers)areas for each task. BTW, your modem is probably hanging up because the DTR signal is going away when you switch to another task. With DV, you can configure a task so it has exclusive access to a particular com port. Not sure how you do that with Taskmgr. Or even if you can. -- Leonard Erickson (aka shadow) shadow at krypton dot rain dot com
