39 devices of the sequential access class that are attached to the system
43 The sequential access class includes tape and other linear access devices.

80 It should be noted that tape devices are exclusive open devices, except in
84 .Sh SUB-MODES
86 .Sq sub-modes .
87 The sub-modes differ in the action taken when the device is closed:
88 .Bl -tag -width XXXX
112 block-size modes.
114 .Tn QIC Ns -type
115 devices run in fixed block-size mode, where most nine-track tapes and
116 many new cartridge formats allow variable block-size.

158 process to read if in no-rewind mode.)
175 The problem with that behavior, though, is that it hides the actual on-tape
