thanks Ken and Eric. Problem solved!
I found out that it was tset that screwsed up the tab setting. And it cannot be fix with tset or reset.
tabs -8 can fix it.
But, if I change the TERM from dtterm to vt100 and issue a tset, the tab settings will be fine.
I still don't know what's going on, but thanks to your help, the problem is solved.
