     Be careful about placing DOS into RAW mode.  In some versions of DOS
(I don't know about the latest versions), using certain DOS functions while
you are in RAW mode will cause DOS to HANG.  I can't remember which DOS
calls will do this (I think they are DOS handle read/write fcns) but, if
anyone is interested, I'll dig up the info.

Example (make sure the system is backed up before this is tried):

     Use a program to place the console in RAW mode.  Then run LINK.  Your
machine will hang and require a reboot.
