Summary: Sure.  It's called "copy"

Sure.  COPY can write to a terminal just like a file.  Or a magtape.
Or whatever else might be on line.
	
For example, to write to the equivalent of /dev/tty3 (txa3:) on a MicroVAX:
	
$ copy foo.tex txa3:

You DO need physio priviledge to do this, if the terminal line isn't set
up as an assignable device.  If it is set up as assignable, you just
ALLOCate txa3: and then COPY your file to it.
	
You probably want to set the TX line to HOSTSYNC and READSYNC so that
when whatever-it-is on the other end is in danger of overrunning, it will
send ^S-^Q signals.  If the other end is a Unix machine, 'stty tandem' 
will do the trick.
 
You can even do this COPYing trick to a line that is ALLOCated to 
another user, or to a line that is being used for SET HOST/DTE, if
you have enough privs.  I know that works too; I move my resume around
that way.
