Signal Status
Signal Status
Read security: 5
Shows the status of key DTE interface signals. An asterisk (*) indicates the presence of a signal and a
hyphen (-) indicates no signal present.
Port Operating port number.
DTE Signals The following signals are monitored (these options are read-only):
I/O Status
Write security: 5; Read security: 5
Displays the input/output statistics for the Async-232 ports.
Port Displays the port number.
Tx Bytes Displays the number of bytes transmitted by the DTE.
Rx Bytes Displays the number of bytes sent to the DTE.
Overruns Displays the received overrun errors from the DTE. A receiver overrun occurs
when the DTE performs data transmission too fast for the Async-232 port to
keep up, therefore causing data to be lost. An overrun may indicate the need to
turn on hardware flow control.
PrtyErrs Displays the number of bytes received from the DTE that contained parity
errors.
FrmErrs Displays the number of bytes received from the DTE that contained framing
errors.
Rst Stats Clears the current stored I/O statistics for each port.
