Dear SCO Customer,

Support Level Supplement (SLS) PTF7090A, the Replacement rsh Supplement, 
corrects the problem of a potential process hang when rsh is used heavily.
This was originally observed when thousands of print jobs were being issued 
remotely where rsh was called.  SLS PTF7090A provides a modified /usr/bin/rsh
which fixes this problem.

SLS PTF7090A contains:

        /usr/bin/rsh
