The problem is that cleartool was written to run in a Windows
console, not in the kind of pty terminal interface that Unix
terminals and the Cygwin rxvt and xterm terminals provide.  Some
cleartool commands just print to stdout, and those will work fine in
a pty terminal.  When cleartool prompts for user input, however, it
uses the Console interface, which doesn't work in a pty.

There was a thread about this issue in this list in March 2008.

What I've done is to write a wrapper bash script around cleartool
that "intercepts" commands that require user input and either
manages the user input dialog itself or prints a message telling the
user to use a Windows Command Prompt or use a non-interactive form
of the command.

Regards,
Gary
