Lets suppose I have a desktop computer. Is there any way (i.e. a PCI card or some kind of software/hardware) through which I can enable the computer to support serial redirection?
By serial redirection I mean: plug in a serial cable to the desktop computer, so that what is shown on the desktop computer's screen flows through the serial cable to other computer.
//Edit: to explain what I want to achieve a little more:
I'd like to see the boot process / the OS loading procedure by using the serial cable. The scenario is more or less like this: lets suppose I have a desktop computer I'm using as a server. The server is a Windows / Linux machine. Lets also suppose the machine has no monitor attached. And, lets suppose I messed up with iptables / windows firewall rules and I'm not able to connect to the machine 'remotely'. I'd like to use the serial port to log in to the machine and make appropriate changes to the firewall rules. If I could also see the boot process over that cable, (and fix boot process related errors thanks to that) it would be even more awesome.
Hello, this question is pretty old, but did you solve your problem? – Tarator – 2016-10-20T04:35:53.750
@Tarator at that point I've abandoned the issue. But looking back, like sawdust and Bon Gart have written, it looks like it is possible to specify a serial console connection in Windows (i.e. through boot.ini) and in Linux (by using kernel command line parameters), so that one of COM ports of the PC acts as the 'serial console' port. Usually, stuff like Cisco routers / Wifi routers (i.e. ones running OpenWRT) (vs casual PCs) have that serial connection preconfigured on one of the serial ports.

For Linux the console device can be (or has to be?) specified in the kernel command line passed by the bootloader. A serial port is typically specified as the console when there is no display adapter. – sawdust – 2012-05-06T23:56:16.927
