     NAME
          ik - Ikon 10088 hardcopy interface controller

     SYNOPSIS
          /dev/cent
          /dev/vp0

     DESCRIPTION
          This is the driver for the Ikon 10088 (and 10088A) hardcopy
          interface controller.  The controller can support any one of
          three possible interfaces:  Versatec TTL, Versatec
          differential, or (Tektronix-compatible) Centronics.  The
          Ikon controller board must be jumpered, switched, connected,
          and terminated differently depending on which interface is
          being used.

          If the board is configured for the Centronics interface,
          bytes written to /dev/cent are output to the hardcopy port.
          A printer reset (input prime) is issued when the device file
          is opened.

          If the board is configured for either Versatec interface,
          bytes written to /dev/vp0 are output to the hardcopy port.
          A printer reset is issued when the device file is opened.
          In addition, the following Versatec control calls are
          provided via ioctl(2).  The relevant definitions are
          contained in the include file <sys/vcmd.h>.

          ioctl(fd,VSETSTATE,int_3_ptr);
               changes the Versatec device state according to the
               contents of the 3 integers pointed at by int_3_ptr.
               The first integer specifies a Versatec command:
               VPRINT commands the Versatec device to enter print mode;
               VPLOT commands it to enter plot mode;
               VPRINTPLOT commands it to enter simultaneous print/plot mode;
               VLF commands it to output a linefeed;
               VFF commands it to output a formfeed;
               VREOT drives the remote EOT signal.
               The second integer specifies a timeout delay (in
               seconds) for subsequent Versatec operations, including
               output operations.  A specified delay of 0 is ignored.
               The default delay is 300 seconds.  This may be
               insufficient for large and / or slow devices.  The
               third integer is ignored.

          ioctl(fd,VGETSTATE,int_3_ptr);
               passes back Versatec device state information in the 3
               integers pointed at by int_3_ptr.  The first integer
               contains:
               VPRINT if the Versatec device is in print mode;
               VPLOT if it is in plot mode;
               VPRINTPLOT if it is in simultaneous print/plot mode.

               The second integer contains the current timeout delay
               (in seconds) (see VSETSTATE above).  The third integer
               is not used.

          It is normally unnecessary to use /dev/cent or /dev/vp0
          directly; the spooling software (see lp(1)) provides an
          adequate interface.
