1.10 +** Test socket IO timeouts
1.11 +**
1.12 +**
1.13 +**
1.14 +**
1.15 +** Modification History:
1.16 +** 14-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.
