There's a telnet = option which =0A= maps EOL to <CR><LF>;  You'll want to

I'm now writing that same module in Python. It is to allow customers to use python scripts when interfacing with consoles. I'm new at Python (3 days) so there are no exception programming and it might not be the best form. Feel free to add support for 8.X conserver since I only use 7.X and add exceptions.

The only console access I seem to be able to find is: 1) Via the Ethernet MGMT interface where you connect via the web browser and start their JAVA remote console process. A nice feature, but not compatible with conserver. 2) Via the Ethernet (or Serial) MGMT interface and you: a) Log into the ILOM b) run "start /SP/console" and answer "y" to the question. ...and I am not even sure if this works. We seem to be rolling these machines out at a pretty regular pace, so I *really* would like to get them working with my conserver setup. Help!

You can use a connect script like: #!/usr/local/bin/expect -f expect { "(yes/no)?" {exp_send "yes\r"; exp_continue; } "password: " {exp_send "\r"; } } expect "\\-> " send "cd /SP/console\rstart\r" expect "(y/n)?" exp_send "y\r" I then have the conserver setup stuff like: console foo { include ilom; exec ssh -l admin foo-ilom; type exec; initcmd "/path/to/above/script"; } That seems to be working fine for us.

Of course this does not work = because conserver gets an I/O error (as does agetty) when trying to = wrestle for control of the port.

P.S. The motherboard has only = one serial port and we can't add more hardware.  Otherwise I would = install a null-modem jumper between the two serial ports and use = conserver's access to one to log into the other.  Oh = well.

You need to be connected physically to the serial port. One idea is to attach a serial cable from ttyS0 -> ttyS1.
