                     17: .SH DESCRIPTION
                     18: The MPCC has two different connecter panel styles.
                     19: The 16 port MPCC will support any combination of SYNC or ASYNC ports.
                     20: The 32 port MPCC will only support ASYNC ports.
                     21: Each async line attached to the MPCC communications controller
                     22: behaves as described in
                     23: .IR tty (7)
                     24: and may be set to run at any of 16 speeds; see
                     25: .IR tty (7)
                     26: for the encoding.
                     27: .PP
                     28: Each MPCC controller uses 2 consecutive entries in the SCB for
                     29: download/handshake, and command/response interrupts.  These entries
                     30: start at 0xa0 for the 1st controllers download/handshake interrupts
                     31: and 0xa1 for the 1st controllers command/response.
                     32: .PP
                     33: The MPCC controller requires a firmware download to be completed
                     34: before it can function.  See \fIdlmpcc\fP(8) and \fImpcctab\fP(4)
                     35: for specific information on how to configure and download the
                     36: firmware into the MPCC controller.
                     37: .PP
                     38: A maximum of 16 MPCC communication controllers can be supported.

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