SEG(1)                                                     SEG(1)

     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 per-
          formed whatsoever.  Odd values may cause the front to fall
          off.
