	Why not just change the baud rate from the default 2400 down to
1200?  That's what we did on our 750/LA-120 combo (down with LA-100's!).
The printer can keep up without ever having to send a C-S, and 1200 is
plenty fast enough anyway (in fact, if you make the console 300, that might
be better because it disuades people from using it as a regular terminal).

	The only problem with this is that to change the console baud rate
you have to move jumpers on the CPU backplane.  Why DEC did this, I'll
never know.  BTW, on the 2 Vax installations I've supervised, the tech
doing the install had the baud rate on the console set wrong and refused to
believe that was the problem (they prefer to take the whole CPU apart).
