NAME
     tpqic - ISI QIC-02 1/4 inch cartridge tape driver

SYNOPSIS
     {
          "tpqic",  tpqicinit,    tpqicopen,
          tpqicstrategy,     tpqicclose,   tpqicioctl,
          DTTYPEBLOCK,
          DTFSAUTO,     "Integrated Solutions QIC-02 tape"
     }

DESCRIPTION
     Tpqic is the driver for the Integrated Solutions QIC-02 1/4
     inch cartridge tape controller.  The tpqic driver supports a
     single tape drive per controller.

REGISTERS
     Controller 0 is assumed to be at address 0xfff550 in VME A24
     supervisor address space (address modifier 0x3D).  Con-
     troller 1 is assumed to be at address 0xfff560 in VME A24
     supervisor space.  The user can access other tpic controll-
     ers with control registers at addresses other than these by
     specifying the negative of the control register base address
     as the controller number.

IOCTLS
     Currently the tpqic driver supports no special ioctls.

DIAGNOSTICS
     The following diagnostics are printed by the tpqic driver:

     tpic bad controller number %d
          A controller number greater than 1 was specified

     tpic bad unit number %d
          A unit number other than 0 was specified

     no cartridge tape controller at 0x%x
          The tape controller hardware did not respond to refer-
          ences to control registers at the address shown

     tpqic(%d) in use
          The tape controller was opened on a second descriptor
          while already in use

     tpqic(%d) not online
          An open was attempted with no tape cartridge in the
          tape drive

     Failed to read in volume header
          A tape error was detected that prohibited reading the
          tape directory

     bad volume header
          The tape directory was not present, incorrectly format-
          ted, or checksummed incorrectly

     tpqic(%d) never came ready
          The tape controller never indicated that it was ready
          to accept a command

     Numerous other errors can be reported that indicate failure
     of the tpic hardware or I/O failures due to bad media.
