I/O Status

I/O Status fields show statistics for all ports on the module (see Figure 3-5). Sta-
tistics may be reset on a per-port basis. In all fields, the RX direction refers to data
flow from the Async-232 Module ports towards the DTE. The TX direction refers
to data flow from the DTE towards the Async-232 Module ports. Statistics are
kept since the last powerup or reset statistic command. Descriptions of the avail-
able statistics and control fields follow.
TX-Bytes
Read security: 5
Displays the number of bytes received from the DTE.
RX-Bytes
Read security: 5
Displays the number of bytes transmitted to the DTE.
Overruns
Read security: 5
Displays the number of receiver overruns encountered on the port from the DTE.
A receiver overrun occurs when the DTE performs data transmission too fast for
the ATLAS port to keep up, therefore causing data to be loss. An overrun may
indicate the need to turn on hardware flow control.
Prty Errs (Parity Errors)
Read security: 5
Displays the number of received characters with parity errors from the DTE.
