NAME

wt − cartridge tape device

DESCRIPTION

The wt device driver provides the interface to an AT cartridge (streaming) tape device.  When opened for reading or writing, the tape is presumed to be positioned as desired for the operation.  On close, the tape is rewound or left at the current position depending on the device selection.  To rewind the tape, use the rewind-on-close device. 

Ioctl Calls

One ioctl command, WTQICMD, is available, with two possible arguments (see <sys/wtioctl.h>):

ERASE This call erases data on the tape cartridge. 

RETENS This call is used to “retension” tape in the cartridge. 

FILES

/dev/tape       /* rewind on close */
/dev/ntape      /* no rewind */

NOTES

At present the driver supports Wangtek and Bell Technologies compatible tape controller cards.
