 * ISATTY.C, by Robert L. Pyron
 *
 * Naive implementation of isatty() for Amiga using Lattice C 5.05.
 * See the following message excerpt (from BIX) about why this
 * approach may not be such a good idea...

 * As for isatty(), IsInteractive may not be the best choice for what you
 * want.  It returns True for prt:.  You may wish to consider sending a
 * ACTION_INFO packet or an ACTION_RAWMODE packet to the handler and see
 * if it returns ACTION_NOT_KNOWN or not.  Whawes can verify the best choice
 * of packets to use for the test.
