If you are booting with a serial console, generally the kernel will autodetect this. If you have a videocard (framebuffer) and a keyboard also attached to the computer which you wish to boot via serial console, you may have to pass the <userinput>console=<replaceable>device</replaceable></userinput> argument to the kernel, where <replaceable>device</replaceable> is youra serial device of the target, which is usually something like <filename>ttyS0</filename><footnote> <para> In order to ensure the terminal type used by the installer matches your terminal emulator, the parameter <userinput>TERM=<replaceable>type</replaceable></userinput> can be added. Note that the installer only supports the following terminal types: <literal>linux</literal>, <literal>bterm</literal>, <literal>ansi</literal>, <literal>vt102</literal> and <literal>dumb</literal>. The default for serial console in &d-i; is <userinput>vt102</userinput>. </para> </footnote>.
