Re: [PMP] Printer MIB question

[Ira McDonald <[e-mail]>]

Hi folks,

No - Bill Wagner had it right in his original reply.

Right after Bill's previous quotation, RFC2790 says:

  "Bits are numbered starting with the most significant
  bit of the first byte being bit 0, the least significant bit
  of the first byte being bit 7, the most significant bit of
  the second byte being bit 8..."

Read the above carefully!

Bit 0 (0x8000) and bit 14 (0x0004) are set.

Cheers,
- Ira (co-editor of Printer MIB v2, RFC 3805)
