Serial Terminal Communication to BMC or DRAC Serial Terminal Mode allows you to directly connect to the BMC or DRAC using a serial port connection and execute text-based commands. Refer to the Appendix B for information about configuring your BMC and DRAC for Serial Terminal Communication as well as available Terminal Mode Commands. In Terminal Mode, the BMC or the DRAC, if present, support Escape key sequences that allow switching between the Serial Terminal Connection and the connection to the system COM2 port. This can be combined with the Console Redirection via COM2 (see "Console Redirection Via COM2") to switch between viewing the system console redirection and communicating to BMC or DRAC to execute the terminal commands such as system reset. NOTE: For this combined functionality, Serial Communication baud rate and the SOL baud rate must be set to the same value. When in terminal mode, to switch the connection to the system COM2 port use: + When connected to the system COM2 port, to go back to the terminal mode use: + SPCR Table The Serial Port Console Redirection (SPCR) table provides information about how the system firmware and service processor use the out-of-band (OOB) management port. For example, if the OOB Management port is a serial port, the SPCR table contains information such as serial port number, baud terminal type, and other settings used for OOB communication. The SPCR table is read by the Special Administrative Console (SAC) for console redirection and configures itself automatically during a bootable CD installation. The SPCR table is automatically enabled if the system service processor supports Emergency Management Services (EMS) such as console redirection. If it is not configured automatically, you must configure SPCR to match BMC settings by adding the following parameters to the unattend.txt file. NOTE: The unattend.txt file is automatically created after installation. 126 Serial Port Console Redirection
