michael@0 8 ** Name: tmocon.c
michael@0 9 **
michael@0 10 ** Description: test client socket connection.
michael@0 11 **
michael@0 12 ** Modification History:
michael@0 13 ** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
michael@0 14 ** The debug mode will print all of the printfs associated with this test.
michael@0 15 ** The regress mode will be the default mode. Since the regress tool limits
michael@0 16 ** the output to a one line status:PASS or FAIL,all of the printf statements
michael@0 17 ** have been handled with an if (debug_mode) statement.
