    1.11 +** Name: tmocon.c
    1.12 +**
    1.13 +** Description: test client socket connection.
    1.14 +**
    1.15 +** Modification History:
    1.16 +** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
    1.17 +**	         The debug mode will print all of the printfs associated with this test.
    1.18 +**			 The regress mode will be the default mode. Since the regress tool limits
    1.19 +**           the output to a one line status:PASS or FAIL,all of the printf statements
    1.20 +**			 have been handled with an if (debug_mode) statement.
