Do I have the wrong cable? I think it's one of those ones used to attach to Cisco equipment, 9-pin RS-232 to RJ-45.<div><br></div><div>I had it working, briefly, but it stopped again. I think it had booted from the CD, and was pouring out messages about a buffer overflow plus a language-selection menu (repeatedly) as fast as 9600 bps would allow. Then I removed the CD and rebooted and now nothing. With a Sun Fire, shouldn't I be able to turn the front-panel switch to "Normal" and press the power button? I did that, and I'm getting nothing on the serial interface. I should be getting POST messages at least.<br>

Turn off hardware flow control (RTS/CTS or DTS/DSR) and use software flow control (XON/XOFF) instead.<br>
Also, if you don't want to use minicom, (the modem AT initialization is a pain to turn off completely) just use screen instead:<br>
"screen /dev ttys0 9600"<br>
