NAME    [Toc]    [Back]

     ppi - HP-IB printer/plotter interface

SYNOPSIS    [Toc]    [Back]

     ppi0 at hpibbus0 slave 5 punit 0

DESCRIPTION    [Toc]    [Back]

     The ppi interface provides a means of communication with HPIB printers
     and plotters.

     Special  files  ppi0 through ppi3 are used to access the devices, with the
     digit at the end of the filename referring to  the  bus  address of the device.
   Current  versions of the autoconf code can not probe
for these devices,
 so the device entry in the configuration file must be
fully qualified.

BUGS    [Toc]    [Back]

     This  driver  is very primitive, it handshakes data out byte
by byte.  It
     should use DMA whenever possible.
