        !            33: .SH DESCRIPTION
        !            34: The MPCC has two different connecter panel styles.
        !            35: The 16 port MPCC will support any combination of SYNC or ASYNC ports.
        !            36: The 32 port MPCC will only support ASYNC ports.
        !            37: Each async line attached to the MPCC communications controller
        !            38: behaves as described in
        !            39: .IR tty (7)
        !            40: and may be set to run at any of 16 speeds; see
        !            41: .IR tty (7)
        !            42: for the encoding.
        !            43: .PP
        !            44: Each MPCC controller uses 2 consecutive entries in the SCB for
        !            45: download/handshake, and command/response interrupts.  These entries
        !            46: start at 0xa0 for the 1st controllers download/handshake interrupts
        !            47: and 0xa1 for the 1st controllers command/response.
        !            48: .PP
        !            49: The MPCC controller requires a firmware download to be completed
        !            50: before it can function.  See \fIdlmpcc\fP(8) and \fImpcctab\fP(4)
        !            51: for specific information on how to configure and download the
        !            52: firmware into the MPCC controller.
        !            53: .PP
        !            54: A maximum of 16 MPCC communication controllers can be supported.

        !            61: .SH BUGS
        !            62: As of the 4.3BSD-tahoe release, only 16 port mpcc's work, and then
        !            63: only in async mode.  Attempting to reload firmware on an mpcc with
        !            64: active ports may crash the system.  This should be fixed within
        !            65: a short period of time; contact the CSRG at University of California,
        !            66: Berkeley, for upgrade information.
