No. The problem is that cleartool is written for Windows (i.e. DOS or 
cmd) which does not use ptys. rxvt, and apparently XEmacs both use ptys. 
The only solution is to get Rational to fix cleartool (or to use a DOS 
box - or to specify all parameters on the command line so that there is 
no prompting).
