wt -- Archive/Wangtek cartridge tape driver
wt0 at isa? port 0x300 irq 5 drq 1
The wt driver provides support for the following Archive and Wangtek
Raw devices are indicated by an ``r'' preceding the device name. The
driver can be opened with either rewind on close (/dev/rst*) or no rewind
on close (/dev/nrst*) options.
The tape format is specified by adding 8 or 16 to the device number. For
example, for the wt0 device's raw rewind on close device nodes, /dev/rwt0
is the 150 MByte density device, /dev/rwt8 is the 120 MByte density
device, and /dev/rwt16 is the 60 MByte device.
The wt driver conflicts unpleasantly with the we driver (SMC Ethernet
adapters) at the same I/O address. The probe reprograms their EEPROMs.
