Have you tried doing an explicit flush on the socket?  So you would have
the following?

# CLIENT.RB 
# ========= 
require 'socket' 
s=TCPSocket.new("localhost", ARGV[0]) 
s.write("test\n") 
s.flush
puts s.gets 
s.close()

# SERVER.RB 
# ========= 
require "socket" 
gs = TCPserver.open(0) 
printf("server is on port %d\n", gs.addr[1]) 
s = gs.accept 
line = s.gets
puts line
s.write(line.upcase) 
s.flush
s.close

I don't have access to an OpenVMS machine myself so I'm just throwing
out ideas here.
