Access ESXi console from iDRAC (dell)

ESXi 5.5 Dell Version 5.5.0-1623099

Dell R715, iDRAC 6.

I connect to iDRAC console over SSH.

From iDRAC console I want to reach ESXi console.

For this purpose I have set following in BIOS: https://s31.postimg.org/5gn927oyz/Dell_Bios.png

Then, uder iDRAC I have set following:

    racadm config -g cfgSerial -o cfgSerialBaudRate 9600

    racadm config -g cfgSerial -o cfgSerialCom2RedirEnable 1

    racadm config -g cfgSerial -o cfgSerialSshEnable 1

    racadm config -g cfgIpmiSol -o cfgIpmiSolEnable 1

    racadm config -g cfgIpmiSol -o cfgIpmiSolBaudRate 9600

That should allow me in iDRAC to execute: console com2 and access ESXi console (text).

Instead of that I have blank screen. Here is an example: https://s31.postimg.org/8ivyc7hej/console.png

Did anyone managed hoe to do that or see what mistake I did here ?
