fw-rom-revision – HP-LASERJET-COMMON-MIB

Object

scalar mandatory SNMPv2-TCDisplayString

This identifies the system code firmware ROM revision code. The
format for a revision is major_revision.minor_revision. There
may be other ROM revision code objects for other specific ROMs
such as font ROMs, localization ROMs, etc; these other ROM
revision code objects are device specific.

Syntax

SNMPv2-TCDisplayString

Source: SNMPv2-TCDisplayString
Base type: OctetString
Display format: 255a

Type Description

Represents textual information taken from the NVT ASCII
          
character set, as defined in pages 4, 10-11 of RFC 854.
          
To summarize RFC 854, the NVT ASCII repertoire specifies:
          
  - the use of character codes 0-127 (decimal)
          
  - the graphics characters (32-126) are interpreted as
    US ASCII
          
  - NUL, LF, CR, BEL, BS, HT, VT and FF have the special
    meanings specified in RFC 854
          
  - the other 25 codes have no standard interpretation
          
  - the sequence 'CR LF' means newline
          
  - the sequence 'CR NUL' means carriage-return
          
  - an 'LF' not preceded by a 'CR' means moving to the
    same column on the next line.
          
  - the sequence 'CR x' for any x other than LF or NUL is
    illegal.  (Note that this also means that a string may
    end with either 'CR LF' or 'CR NUL', but not with CR.)
          
Any object defined using this syntax may not exceed 255
characters in length.
