The controller provides high-speed
synchronous communications for the

This utility allows you to 
download any or all of the
.Tn MPCC

the protocol attributes for each
.Tn MPCC
board. See
.Xr mpcctab 4

and downloads all configured boards
with corresponding protocol software.

.Pp
.Dl dlmpcc  2
.Pp
The next command line orders the download of the protocols identified with
boards 0 and 3: 
.Pp
.Dl dlmpcc  0  3
