PTCWCT - Terminal control write counter
This counter is incremented by the driver every time a control write buffer for this terminal is transferred to the Mux interface card.
PTTXCT - Terminal transmit message counter
This counter is incremented by the driver every time a transmit buffer for this terminal is transferred to the Mux interface card.
PTRXCT - Terminal receive message counter
This counter is incremented by the driver every time a receive message is transferred from the Mux interface card for this terminal.
PTERCT - Terminal error message counter
This counter is updated by the driver after each $STDT buffer has been transferred from the Mux interface card. The $STDT buffer contains the number of errors that have occurred for a terminal since the last $STDT buffer was sent to the driver.
