    Hi Bert,

    Thanks for your quick feedback. My replies inline below.

    Won't work, because this port is not limited to Internet Suite
    protocols. The 'service:' URI in ppmPortServiceNameOrURI may
    also be for non-Internet suites (AppleTalk, NetWare, etc.).

    I'll correct the DESCRIPTION in the MIB and make clear that
    (as with the Printer MIB) ports/channels may be from multiple
    protocol suites.

    Won't work. PrtChannelTypeTC currently only defines 'other(1)'
    and (foolishly) does NOT define 'unknown(2)' (unlike every other
    textual convention in the Printer MIB). Because the Printer MIB
    v2 still doesn't define DEFVAL clauses for most objects, this
    oversight has not surfaced before. We could register 'unknown(2)'
    with IANA, but _not_ fast enough (because this MIB's going into OS
    and printer vendor products right now).

    Agreed. My mistake from the old Printer MIB (RFC 1759).

    I'll correct the references in the MIB.
