  *  This file should contain stubs for any of the TCP/IP functions perl5
  *  requires which are not supported by your TCP/IP stack.  These stubs
  *  can attempt to emulate the routine in question, or can just return
  *  an error status or cause perl to die.
  *
- *  This version is set up for perl5 with socketshr 0.9D TCP/IP support.
+ *  This version is set up for perl5 with UCX (or emulation) via
+ *  the DECCRTL or SOCKETSHR 0.9D.
