NAME
       seg - access a named segment

SYNOPSIS
       seg [ -WLrw ] segment segment-size offset [ value ]

DESCRIPTION
       seg  accesses a named segment as provided by e.g. certain drivers.  The
       operation to be performed is selected with -r and -w  for  reading  and
       writing,  respectively.  The default operation size is a byte.  C style
       notation for integers (e.g.  0x42 or 023) is accepted for the  segment-
       size, offset and value parameters.

       -W     Perform a word (16 bit) operation

       -L     Perform a long / double word (32 bit) operation.

BUGS
       No check of the segment-size and offset parameters is performed whatso‐
       ever.  Odd values may cause the front to fall off.
