Jeremy:

Thanks for the reply!  Unfortunately flushing the socket seems to have
had no effect.  I think there is something internally, within the socket
implementation for OpenVMS, that is the problem.  Something that I am
not yet familiar with.  (like another post I made to the group regarding
threads: I had only to make an O/S specific define to make ruby threads
work on OpenVMS)  

If I find the answer I'll be sure to post it.  And if you, or anyone
else has any further ideas I'm open to suggestions.  I think I've 
just about exhausted my resources. :)  (But that doesn't mean I'm giving
up.) 

Regards, 
Brad
