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.

HISTORY
The
driver appeared in
BSD 4.1
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.
