There are two, that display different info.  One is where they log in 
and start the application, some of its output goes to SYS$OUTPUT, that 
terminal.  The other terminal gets allocated by the application, and 
(different) output goes to it.  At this time, both "terminals" are PCs 
running Reflection connected to a serial line.  The serial lines are to 
go away and be replaced by telnet.  The first is trivial, Reflection 
telnets to the host.  The second is what I am dealing with, I'd like for 
the application to connect to the second PC automatically.  Port # 
doesn't matter, I used 23 as it's the standard telnet port.

That's what I will probably wind up doing (captive account).

They want to get rid of hardware.

Thanks everyone for the help so far.
