9 | .SH DESCRIPTION | |
10 | The tm-03/transport combination provides a standard tape drive | |
11 | interface as described in | |
12 | .IR mtio (4). | |
13 | All drives provide both 800 and 1600 bpi; the TE-16 runs at 45 ips, | |
14 | the TU-45 at 75 ips, while the TU-77 runs at 125 ips and autoloads tapes. | |

24 | .SH DIAGNOSTICS | |
25 | \fBtu%d: no write ring\fR. An attempt was made to write on the tape drive | |
26 | when no write ring was present; this message is written on the terminal of | |
27 | the user who tried to access the tape. | |
28 | .PP | |
29 | \fBtu%d: not online\fR. An attempt was made to access the tape while it | |
30 | was offline; this message is written on the terminal of the user | |
31 | who tried to access the tape. | |
32 | .PP | |
33 | \fBtu%d: can't switch density in mid-tape\fR. An attempt was made to write | |
34 | on a tape at a different density than is already recorded on the tape. | |
35 | This message is written on the terminal of the user who tried to switch | |
36 | the density. | |
37 | .PP | |
38 | \fBtu%d: hard error bn%d mbsr=%b er=%b ds=%b\fR. A tape error occurred | |
39 | at block \fIbn\fR; the ht error register and drive status register are | |
40 | printed in octal with the bits symbolically decoded. Any error is | |
41 | fatal on non-raw tape; when possible the driver will have retried | |
42 | the operation which failed several times before reporting the error. | |
43 | .SH BUGS | |
44 | If any non-data error is encountered on non-raw tape, it refuses to do anything | |
45 | more until closed. |
