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. | |

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. | |
