NAME
ts - TS-11 magtape interface

SYNOPSIS
/sys/conf/SYSTEM:
	NTS	ts_drives		# TS11
/etc/dtab:
	#Name	Unit#	Addr	Vector	Br	Handler(s)		# Comments

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 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 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).
