The DAM maintains the port status to determine the usability of a port/subchannel. A port/subchannel is operating normally if the status value is zero. If it is out of transmit buffers, no new transmit data transfer will be initiated. If the port/subchannel is disabled, down or undefined, the DAM will ignore all processing for this port.

IPCNTR - Terminal count per port/subchannel

This field contains the number of terminals defined on each port/subchannel of this Mux interface card. It is initialized by TTGEN based on the number of Term entries in the TTGEN configuration file and is kept for informational purposes only.
