dt is a generic data test program used to verify proper operation of
|
|
peripherals, file systems, device drivers, or any data stream supported
|
|
by the operating system. In its simplest mode of operation, dt writes
|
|
and then verifies its default data pattern, then displays performance
|
|
statistics and other test parameters before exiting. Since verification
|
|
of data is performed, dt can be thought of as a generic diagnostic tool.
|
|
|
|
dt has been used to successfully test disks, tapes, serial lines,
|
|
parallel lines, pipes, and memory mapped files. In fact, dt can be used
|
|
for any device that allows the standard open, read, write, and close
|
|
system calls. Special support is necessary for some devices, such as
|
|
serial lines, for setting up the speed, parity, data bits, etc.
