47 NOTE: This driver has not been ported from
53 transport combination provides a standard tape drive
54 interface as described in
56 All drives provide both 800 and 1600
73 .It tu%d: no write ring.
74 An attempt was made to write on the tape drive
75 when no write ring was present; this message is written on the terminal of
76 the user who tried to access the tape.
79 An attempt was made to access the tape while it
80 was offline; this message is written on the terminal of the user
81 who tried to access the tape.
83 .It tu%d: can't change density in mid-tape.
84 An attempt was made to write
85 on a tape at a different density than is already recorded on the tape.
86 This message is written on the terminal of the user who tried to switch
89 .It "tu%d: hard error bn%d mbsr=%b er=%b ds=%b."
93 the ht error register and drive status register are
94 printed in octal with the bits symbolically decoded. Any error is
95 fatal on non-raw tape; when possible the driver will have retried
96 the operation which failed several times before reporting the error.
113 May hang if physical (non-data) errors occur.
