Another drawback of putting the console in raw mode is that some
programs don't like it.  I found this out the hard way when I put the
console in raw mode and then tried to use Microsoft Link version 3.02. 
Nothing I typed at Link's prompts would be read.  Since ^C and ^Break
were disabled, the only way out was Ctrl-Alt-Del.  Running with the
console in raw mode is fine if you are careful, but beware of programs
which don't like it.  Remember, you don't have ^C anymore.
