RE: Installing Linux on a E250 with serial console: cannot get the boot prompt

do you have the telnet card in the machine? and if its configured you wont
get anything from the serial connection in normal power-on mode. I had this
problem and just removed the card and then I had serial output.

Subject: Installing Linux on a E250 with serial console: cannot get the
boot prompt


Hello, everybody,

I try to boot a Sun E250 which has no monitor or keyboard. Following
the instructions in the UltraLinux FAQ
<URL:http://www.ultralinux.org/faq.html>, I configured a PC with
FreeBSD and minicom to act as the serial console. (I also tried
minicom on a RedHat, without more success.)

When I power on the machine in the Diagnostics position, I see the
boot messages. So my cables and emulator are OK. But sending Break
with Ctrl-A F does not seem to have any result: I cannot get the boot
prompt (ok).

When I power on the machine in Power-On mode, I get nothing on the
screen, not one message.

Last screen of messages in Diagnostics mode (after that, nothing
moves):
