rs232Number

The number of ports (regardless of their current state) in the RS-232-like general port table.

rs232PortTable

A list of port entries. The number of entries is given by the value of rs232Number.

rs232PortEntry

Status and parameter values for a port.

rs232PortIndex

The value of ifIndex for the port. By convention and if possible, hardware port numbers map directly to external connectors. The value for each port must remain constant at least from one re-initialization of the network management agent to the next.

rs232PortType

The port's hardware type.

rs232PortInSigNumber

The number of input signals for the port in the input signal table (rs232PortInSigTable). The table contains entries only for those signals the software can detect and that are useful to observe.

rs232PortOutSigNumber

The number of output signals for the port in the output signal table (rs232PortOutSigTable). The table contains entries only for those signals the software can assert and that are useful to observe.

rs232PortInSpeed

The port's input speed in bits per second. Note that non-standard values, such as 9612, are probably not allowed on most implementations.

rs232PortOutSpeed

The port's output speed in bits per second. Note that non-standard values, such as 9612, are probably not allowed on most implementations.

rs232PortInFlowType

The port's type of input flow control. 'none' indicates no flow control at this level. 'ctsRts' and 'dsrDtr' indicate use of the indicated hardware signals.

rs232PortOutFlowType

The port's type of output flow control. 'none' indicates no flow control at this level. 'ctsRts' and 'dsrDtr' indicate use of the indicated hardware signals.

rs232AsyncPortTable

A list of asynchronous port entries. Entries need not exist for synchronous ports.

rs232AsyncPortEntry

Status and parameter values for an asynchronous port.

rs232AsyncPortIndex

A unique value for each port. Its value is the same as rs232PortIndex for the port.

The port's number of bits in a character.

rs232AsyncPortStopBits

The port's number of stop bits.

rs232AsyncPortParity

The port's sense of a character parity bit.

rs232AsyncPortAutobaud

A control for the port's ability to automatically sense input speed. When rs232PortAutoBaud is 'enabled', a port may autobaud to values different from the set values for speed, parity, and character size. As a result a network management system may tempo ...

rs232AsyncPortParityErrs

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'.

rs232AsyncPortFramingErrs

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'.

rs232AsyncPortOverrunErrs

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'.

rs232SyncPortTable

A list of asynchronous port entries. Entries need not exist for synchronous ports.

rs232SyncPortEntry

Status and parameter values for a synchronous port.

rs232SyncPortIndex

A unique value for each port. Its value is the same as rs232PortIndex for the port.

rs232SyncPortClockSource

Source of the port's bit rate clock. 'split' means the tranmit clock is internal and the receive clock is external.

rs232SyncPortFrameCheckErrs

Total number of frames with an invalid frame check sequence, input from the port since system re-initialization and while the port state was 'up' or 'test'.

rs232SyncPortTransmitUnderrunErrs

Total number of frames that failed to be transmitted on the port since system re-initialization and while the port state was 'up' or 'test' because data was not available to the transmitter in time.

rs232SyncPortReceiveOverrunErrs

Total number of frames that failed to be received on the port since system re-initialization and while the port state was 'up' or 'test' because the receiver did not accept the data in time.

rs232SyncPortInterruptedFrames

Total number of frames that failed to be received or transmitted on the port due to loss of modem signals since system re-initialization and while the port state was 'up' or 'test'.

rs232SyncPortAbortedFrames

Number of frames aborted on the port due to receiving an abort sequence since system re-initialization and while the port state was 'up' or 'test'.

rs232SyncPortRole

The role the device is playing that is using this port. dte means the device is performing the role of data terminal equipment dce means the device is performing the role of data circuit-terminating equipment.

rs232SyncPortEncoding

The bit stream encoding technique that is in effect for this port. nrz for Non-Return to Zero encoding nrzi for Non-Return to Zero Inverted encoding.

rs232SyncPortRTSControl

The method used to control the Request To Send (RTS) signal. controlled when the DTE is asserts RTS each time data needs to be transmitted and drops RTS at some point after data transmission begins. If rs232SyncPortRole is 'dte', the RTS is an output sig ...

rs232SyncPortRTSCTSDelay

The interval (in milliseconds) that the DCE must wait after it sees RTS asserted before asserting CTS. This object exists in support of older synchronous devices that cannot recognize CTS within a certain interval after it asserts RTS.

rs232SyncPortMode

The mode of operation of the port with respect to the direction and simultaneity of data transfer. fdx when frames on the data link can be transmitted and received at the same time hdx when frames can either be received from the ...

rs232SyncPortIdlePattern
