I'm running GNU Emacs 18.52.2 under VAX/VMS 4.7 on one of several vaxen
connected through a terminal server (DECServer 200).  When emacs starts up
or restarts after being suspended, the terminal server is put in pasthru
mode, but flow control is not disabled.  I can disable flow control
(XON/XOFF) on the server manually, but this is undesirable due to the need
to turn it back on later.

[the reason I _need_ flow control is that I'm writing some graphics
applications for our HDS3200 (Human Design Systems) terminals which can
emulate vt52/vt100/vt220/tek4014 as well as native 4096x4096 resolution
graphics.  the graphics data comes too fast and needs flow control turned
on both on the server and the terminal to work properly -- I've tried
various permutations with both off or only one on and it doesn't work.  the
graphics come out garbled]

My question is who knows what sort of magic is used to get the server to
switch to pasthru mode --- does it do this by sensing the terminal's
condition?  Is there a way to disable flow control _on_the_server_ by an
appropriate termcap entry?
