DTR
The port’s Data Terminal Ready status. Possible values are:
Up - The port is physically prepared to transmit and receive 
packets.
Down - The port is not physically prepared to transmit and 
receive packets. This generally indicates an error condition on 
the circuit.
RTS
The port’s Ready To Send status. Possible values are:
Up - The port is logically prepared to transmit and receive 
packets.
Down - The port is not logically prepared to transmit and 
receive packets. This generally indicates an error condition 
either on the device or the circuit.
CTS
The port’s Clear To Send status. Possible values are:
Up - The port has successfully completed initial line signalling. 
CTS takes place at the end of the initial line signalling process 
and last for a short period of time.
Down - The port has either failed to complete initial line 
signalling or the initial line signalling process has been 
completed.
Invert Tx Clock
The state of the Tx clock. Possible states are:
On - The Tx clock is inverted.
Off - The Tx clock is not inverted.
Ignore DCD
The signal type monitored to determine the interface’s status. 
Possible values are:
On - The interface monitors DSR/CTS signals and ignores 
DCD signals.
Off - The interface monitors DCD signals.
Transmitter Delay
The delay between the CTS signal and the beginning of transmission.
Loopback
The status of the DTE loopback. Possible values are:
On - DTE loopback is enabled, indicating a line test taking 
place.
Off - DTE loopback is disabled, indicating normal circuit 
operation.
