NAME

pcl − parallel communications link interface

DESCRIPTION

Pcl provides the interface to the Digital Equipment Corporation PCL-11B network bus.  This bus can be used to interconnect up to 16 CPU’s, providing relatively fast communication without individual point-to-point connections. 

The interface permits simultaneous bi-directional communication between any machines on the bus.  Additionally, each such path is further subdivided into 8 independent channels.  A control interface is also provided to reduce the line monitoring overhead for a daemon process.
