Dear SCO Customer,

Support Level Supplement (SLS) ptf7053d, the UnixWare 7 netcfg and 
Serial Manager Supplement, provides solutions for all of the problems
listed below.

These problems were also addressed by previous versions of ptf7053:

1. Changing views occasionally hangs - this has been fixed.
   Serial Manager no longer sets the PPP flag for modems.

2. netcfg failed to check that query scripts existed before attempting 
   to execute them. This could result in one or more of the following 
   error messages:

        NETCFG(SendRequest) Backend script error

        Network Configuration Manager error exit code 134

        Error on trying to run scoadmin from the gui, console:
        Error netcfg already running

3. A mechanism is provided for third-party serial ports to use different 
   device nodes than those previously enforced by the Serial Manager.  
   This requires thatthe vendor supply a Stanza file as part of their 
   driver installation.

SLS ptf7053d addresses this additional problem:

4. Unconfiguring the network adapter that is assigned to the system 
   nodename would result in removal of the /etc/hosts entry for the 
   nodename. This may result in a variety of symptoms, such as error 
   pop-up windows when starting CDE.
