expect difference between SLES9 and SLES8

Does any one know what's different between SLES9 ppc's expect and SLES8 ppc's? I have a expect script which are run correctly in SLES8 ppc, but in SLES9 ppc, it cannot match anything it expects. In deed, I can see the expected string is passed to the expect script. But the expect scripts in SLES9 ppc cannot match it. By replace SLES9's tcl package with SLES8's, it works well. I have ever tried this problem in SLES9 ppc beta2a and SLES9 beta3, it is the same problem. -- USTC Alumni Email System
