+/***********************************************************************
+**
+** Name: tmocon.c
+**
+** Description: test client socket connection.
+**
+** Modification History:
+** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+** The debug mode will print all of the printfs associated with this test.
+** The regress mode will be the default mode. Since the regress tool limits
+** the output to a one line status:PASS or FAIL,all of the printf statements
+** have been handled with an if (debug_mode) statement.
