NAME

ts − TS-11 magtape interface

SYNOPSIS

TS0 at address 0x3ff550/017772520 vector 0x94/0224

DESCRIPTION

The ts-11 combination provides a standard tape drive interface as described in mtio(4). It supports one transport is possible per controller.

SEE ALSO

tar(1), tp(1), mtio(4), tm(4),

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. 

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); 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.
