#### Port Monitor Fields

Field | Description
Type | The type of port selected.
Speed | The speed of the port in bits per second.
Input Flow Control | The input flow control of the port. Examples: none, xonXoff or ctsRts
Output Flow Control | The output flow control of the port. Examples: none, xonXoff or ctsRts
Character Bits | The number of bits in a character. Examples: 8 or 7
Stop Bits | The number of stop bits. Examples: one, two or oneAndHalf
Parity | The type of parity. Examples: none, odd or even
Administrative Status | The administrative status of the port. enabled - Indicates the port is enabled for login. disabled - Indicates the port is not enabled for login.
Operational Status | The operational status of the port, independent of flow control. up - Indicates the network interface may function normally. down - Indicates the network interface is currently unable to function. active - Indicates the port is up and a session is active on the port.
Parity Errors | The total number of characters with a parity error, input from the port since system re-initialization and while the port state was 'up' or 'test'. This field will show a red background if an error has occurred in the last poll interval.
Overrun Errors | The total number of characters with an overrun error, input from the port since system re-initialization and while the port state was 'up' or 'test'. This field will show a red background if an error has occurred in the last poll interval.
Framing Errors | The total number of characters with a framing error, input from the port since system re-initialization and while the port state was 'up' or 'test'. This field will show a red background if an error has occurred in the last poll interval.
Total Characters In | The total number of characters received by the port.
Total Characters Out | The total number of characters transmitted by the port.

#### Signal Monitor

This section of the port monitor window shows the status of various EIA-232 signals on the selected port. Active (on) signals are shown in green and inactive (off) signals in black.

##### EIA-232 Signal Descriptions

Signal | Description
RTS | Request to Send
CTS | Clear to Send
DSR | Data Set Ready
DCD | Data Carrier Detect
DTR | Data Terminal Ready
RI | Ring Indicator
OFC | Output is Flow Controlled
IFC | Input is Flow Controlled

#### Characters In/Characters Out Monitor

The Character In/Character Out graphs show the number of characters received (Characters In) and transmitted (Characters Out) by the port. The graphs update from right-to-left and represent the percentage of line speed over the last 20 poll intervals.

The scale of the graphs can be changed by selecting Options > Graph Scale > Port from the Monitor Window menu.

The poll interval of the graphs can be changed by selecting Options > Poll Interval from the Monitor Window menu. The valid range is from 1-60 seconds. The poll interval determines how frequently the port is polled for information.
