XMT(7M)                                                   XMT(7M)



     NAME
          xmt - Xylogics 1/2 inch magnetic tape controller

     SYNOPSIS
          /dev/mt/xmt*
          /dev/rmt/xmt*

     DESCRIPTION
          This is the driver for the Xylogics Model 772 1/2 inch
          magnetic tape controller.  The driver supports any Cipher
          88X or 99X tape drive.  Reads and writes of up to 30k bytes
          are allowed.  The standard tape ioctl calls are provided
          (see mtio(7m)).  The special files are named according to
          the convention discussed in intro(7m):

              /dev/{r}mt/xmt<controller-#>d<slave-#>{nr}{.density}

          Valid densities are one of 800, 1600, 3200, or 6250. Cooked
          tape files exist in the directory /dev/mt. Raw tape files
          exist in the directory /dev/rmt. For example,
          /dev/rmt/xmt0d0nr.1600 is the name of the raw no-rewind 1600
          bpi tape device.

          Only one of the device files associated with a single drive
          may be opened at a time.

     FILES
