In writing a number of utilities it has become desirable to be able to
tell automatically if stdout has been redirected or not. For example
in writing a directory lister which uses color through the BIOS it
should automatically go back to normal DOS I/O if the device is not
the console. I can do this through fstat or isatty in MSC 3.0 if the
redirected device is a file and not a device, but I can't tell if the
user has redirected stdout to the printer or another device.
Any ideas?
