錯 誤 ! 尚 未 定 義 樣 式 。Intel® <strong>Server</strong> <strong>System</strong> "<strong>Emerald</strong> <strong>Ridge</strong>” Integrated Baseboard Management Controller EPSThe implementation shares serial function with the platform’s COM1 interface. The BMC hascontrol over which agent (BMC or <strong>System</strong>) has access to COM1. Hardware handshaking issupported as are the Ring Indicate and Data Carrier Detect signals.See the Intelligent Platform Management Interface Specification Second Generation v2.0.4.8.1 COM Port SwitchingThe integrated SIO is used for Com port sharing. It has two legacy UARTs and a MUX switchingarrangement that permits the BMC to monitor and intercept the serial traffic on serial port 1(COM1). Note that COM2 is not a supported interface for serial over LAN.If IPMI-over-serial is enabled, then the BMC watches the serial traffic on COM1. This is done torespond to in-band port switching requests.4.8.2 Terminal ModeThe BMC supports terminal mode, as specified in the Intelligent Platform Management InterfaceSpecification Second Generation v2.0. Terminal mode provides a printable ASCII text-basedway to deliver IPMI messages to the BMC over the serial channel or any packet-based interface.Messages can be delivered in two forms:Via hex-ASCII pair encoded IPMI commandsVia text SYS commandsThe terminal mode interface supports a maximum IPMI message length of 40 bytes. The linecontinuation character is supported over the serial channel in terminal mode only. The linecontinuation character is supported for both hex-ASCII and text commands.4.8.2.1 Input Restrictions4.8.2.1.1 Maximum Input LengthThe BMC supports up to 122 characters per line. The BMC stops accepting new characters andstops echoing input when the 122-character limit is reached. However, the , / , illegal, and input newline characters continue to be accepted andhandled after the character limit is reached.4.8.2.1.2 Maximum IPMI Message LengthThe terminal mode interface supports a maximum IPMI message length of 40 bytes.4.8.2.1.3 Line Continuation CharacterThe line continuation character is supported over the serial channel in terminal mode only. Theline continuation character is supported for both hex-ASCII and text commands.4.8.2.2 Command Support4.8.2.2.1 Text CommandsThe BMC supports all the text commands described in the Intelligent Platform ManagementInterface Specification Second Generation v2.0.64Intel ConfidentialRevision 1.1
