This command is defined for tape (drives) and its description +is found in the SSC documents at https://www.t10.org . +.SH OPTIONS +Arguments to long options are mandatory for short options as well. +.TP +\fB\-h\fR, \fB\-\-help\fR +output the usage message then exit. +.TP +\fB\-H\fR, \fB\-\-hex\fR +output response in hex (rather than decode it). +.TP +\fB\-m\fR, \fB\-\-mloi\fR +sets the MLOI bit in the READ BLOCK LIMITS command and if that +succeeds, prints out the Maximum Logical Object Identifier (MLOI) +value.
