怎样获得机器和系统启动过程中的显示消息？

\r\n可以用2台机器连\r\ntip hardwire

Serial port A or serial port B of a tested system is\r\nconnected to another Sun workstation monitor or TTY-type terminal.\r\nTo set up a TIP connection, proceed as follows:\r\n1. Connect serial port A of the tested system to serial port B of a second Sun\r\nworkstation using a serial null modem cable (connect cable pins 2-3, 3-2, 7-20, and\r\n20-7). See FIGURE 3-1.\r\n\r\nFIGURE 3-1 Setting Up a TIP Connection\r\n2-------------3\r\n3-------------2\r\n7----地 地---7\r\n20--地 地--20\r\n\r\n2. At the second Sun workstation, check the /etc/remote file by changing to the\r\n/etc directory and editing the remote file. The following sample remote file\r\ntext shows connection to serial port B:\r\n3. To use serial port A:\r\na. Copy and paste the remote file text that shows connection to serial port B.\r\nb. Modify the pasted text as follows to change the connection to serial port A:\r\nhardwire: /dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:\r\nhardwire: /dv=/dev/term/a:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:\r\n4. In a shell window on the second Sun workstation, type tip hardwire.\r\nThe shell window becomes a TIP window directed to serial port A of the tested\r\nsystem. When power is applied to the tested system, POST messages are displayed\r\nin this shell window.\r\n5. When POST is completed, disconnect the TIP connection as follows:\r\na. Open another shell window at the second workstation.\r\nb. Type ps -a to view the active TIP line and process ID (PID) number.\r\nc. Type the following to disconnect the TIP hardwire process.\r\n% tip hardwire\r\nconnected\r\n% kill -9 PID#
