- * sstest.c
- * A simple tst program for the sample SCSI target driver.
- * To compile: cc (or acc) sstest.c -o sstest
- * Note: the full ANSI conformance flag, -Xt, fails because of the
- * system header files.
- *
- * Usage:
- * sstest [device] [command] [arg]
- * Device is the /devices entry
- * Command can be:
- * open - just open and close the device
- * read [arg] - read a block. If arg is specifed, printf the result
- * write [arg] - write a block. With arg, write "arg"
- * rew - send the SCSI Rewind command (tests the USCSICMD ioctl)
- * tur - send the SCSI Test Unit Ready command (SSTIOC_READY ioctl)
- * errlev [lev] - set the error reporting level to <lev> (see sst_def.h)
