In general, you will find printers that use a serial interface,
Imagewriters, LaserWriters, Diablos, Spinwriters, and HP LaserJets, all
use Xon/Xoff for flow control.  Some of these printers, Imagewriter,
Laserwriter, and HP LaserJet can be modified (easy as flipping a dip
switch on some), to use DTR (DSR??, pin 20 I think), for flow control
the same as the IBM PC.  Some PC's can be configured to use Xon/Xoff
for flow control, like the Zenith PC's.

So beware, if you have a serial interface between units and they cannot
keep up with the line speed, make sure they use the same process for
flow control.
