TS(4)		       BSD/vax Kernel Interfaces Manual			 TS(4)

NAME
     ts — TS-11 magtape interface

SYNOPSIS
     controller zs0 at uba? csr 0172520 vector tsintr
     tape ts0 at zs0 drive 0

DESCRIPTION
     The TS-11 combination provides a standard tape drive interface as
     described in mtio(4).  The TS-11 operates only at 1600 BPI, and only one
     transport is possible per controller.

DIAGNOSTICS
     ts%d: no write ring.  An attempt was made to write on the tape drive when
     no write ring was present; this message is written on the terminal of the
     user who tried to access the tape.

     ts%d: not online.	An attempt was made to access the tape while it was
     offline; this message is written on the terminal of the user who tried to
     access the tape.

     ts%d: hard error bn%d xs0=%b.  A hard error occurred on the tape at block
     bn; status register 0 is printed in octal and symbolically decoded as
     bits.

SEE ALSO
     mt(1), tar(1), tp(1), mtio(4), ht(4), tm(4), mt(4), ut(4)

HISTORY
     The ts driver appeared in 4.1BSD.

BUGS
     May hang ungracefully if a physical error (non-data) occurs.

     The device lives at the same address as a TM-11 (tm(4)); as it is very
     difficult to get this device to interrupt, a generic system assumes that
     a ts is present whenever no TM-11 exists but the CSR responds and a TS-11
     is configured.  This does no harm as long as a non-existent TS-11 is not
     accessed.
