ts

TS(4)							     Kernel Interfaces Manual							     TS(4)

NAME

       ts - TS-11 magtape interface

SYNOPSIS

       /sys/conf/SYSTEM:
	    NTS  ts_drives	# TS11

       /etc/dtab:
	    #Name Unit# Addr   Vector Br Handler(s)	 # Comments
	    ts	  ?	172520 224    5  tsintr 	 # ts11 driver

       major device number(s):
	    raw: 8
	    block: 2
       minor device encoding:
	    bits 0003 specify TS drive
	    bit  0004 specifies no-rewind operation
	    bit  0010 ignored

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.

FILES

       /dev/MAKEDEV	   script to create special files
       /dev/MAKEDEV.local  script to localize special files

SEE ALSO

       mt(1), tar(1), tp(1), mtio(4), ht(4), tm(4), dtab(5), autoconfig(8)

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  termi-
       nal 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 xs1=%b xs2=%b xs3=%b.  A hard error occurred on the tape at block bn; status  registers  0-3  are  printed	in
       octal and symbolically decoded as bits.

       ts%d: addr mod 4 != 0.  The address of a TS-11 command packet was not on an even longword boundary.

BUGS

       If any non-data error is encountered on non-raw tape, it refuses to do anything more until closed.

       The device lives at the same address as a tm-11 tm(4).
