OK,还是下载service手册好好来研究一下。
昨晚已经让机子无显示了，插上键盘鼠标后显示也不出来了，显示器无信号输入，键盘的大小写灯闪烁，是否还必须设置一下才能回到默认的输入输出设备，还是机器已经有其他故障..........

可以用2台机器连
tip hardwire

仔细研究了"Sun Ultra 10 Service Manual",通过打开电源后长按"Stop"键恢复了显示。

看来多看"man"和"manual"好处多多，非常感谢指点！

我想用tip hardwire来连接，"Sun Ultra 10 Service Manual"中有线序图，极其简单，直接找四根网线芯线插入就可临时解决问题，应该不成问题。

我想用DB25-DB25的并口双机直连线（可以通过Windows的直接线缆连接传输文件），不知可不可以，今天开始要工作了，只能再抽空做试验了，虽说弄瘫了也不会有太大的问题，但还是尽量保证能随时弄好。


Setting Up a TIP Connection
A TIP connection enables a remote shell window to be used as a terminal to display
test data from a tested system. Serial port A or serial port B of a tested system is
connected to another Sun workstation monitor or TTY-type terminal.
To set up a TIP connection, proceed as follows:
1. Connect serial port A of the tested system to serial port B of a second Sun
workstation using a serial null modem cable (connect cable pins 2-3, 3-2, 7-20, and
20-7). See FIGURE 3-1.

7----地 地---7
20--地 地--20

2. At the second Sun workstation, check the /etc/remote file by changing to the
/etc directory and editing the remote file. The following sample remote file
text shows connection to serial port B:
3. To use serial port A:
a. Copy and paste the remote file text that shows connection to serial port B.
b. Modify the pasted text as follows to change the connection to serial port A:
hardwire: /dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
hardwire: /dv=/dev/term/a:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:
4. In a shell window on the second Sun workstation, type tip hardwire.
The shell window becomes a TIP window directed to serial port A of the tested
system. When power is applied to the tested system, POST messages are displayed
in this shell window.
5. When POST is completed, disconnect the TIP connection as follows:
a. Open another shell window at the second workstation.
b. Type ps -a to view the active TIP line and process ID (PID) number.
c. Type the following to disconnect the TIP hardwire process.
% tip hardwire
connected
% kill -9 PID#
