Correct Serial Port assigments
Hello Community,
How should I know which settings need to set for my BIOS.SerialCommSettings?
I should has a console connection to the TTYS0.
Set serial shows this:
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3
Is not possible the the ttyS0 should has IRQ3 instead of IRQ4?
Which one should has the correct Serial settings?
Serial Communication : On without Console Redirection
Serial Port Address : Serial Device1=COM2,Serial Device2=COM1
External Serial Connector : Serial Device 1
Failsafe Baud Rate : 115200
Remote Terminal Type : VT100/VT220
Redirection After Boot : Enabled

If you're looking to setup iDRAC access by serial, Stanford wrote up an article on the subject that is pretty detailed. It should be able to serve as an example for you to follow, at least.
https://www.slac.stanford.edu/grp/cd/soft/unix/EnableSerialConsoleAccessViaSSH.htm
What server are you working with and what version of iDRAC firmware? The IRQ number should be hardware assigned.

Hello Dell-DylanJ,
Thanks the article.
My setup is different, I have a serial console monitor tool configured/attached into the serial port. So IDRAC do not use it.
In generally my server serial config looks like that:
COM1 is connected to IRQ3
COM2 is connected to IRQ4
But in this setting the IRQ4 is the first one, and when I have changed to COM1 to COM2 and COM2 to COM1 the signals still unavailable, and after reboot the view is same like as before in my first post.
Tomorrow, I have access to the system again, and post some details.
