= Kernel-Debugging OS/2 as a !VirtualBox Guest = 

With a Linux host and an OS/2 guest in !VirtualBox, the serial terminal für kernel debugging can be established like this:

== 1st Linux Terminal ==

{{{
socat UNIX-CONNECT:./os2dbg PTY,link=./os2dbg 
}}}

where ''os2dbg'' is the name of the host pipe file specified in the serial setup dialog of !VirtualBox.

== 2nd Linux Terminal ==

{{{
screen -h 400 ./os2dbg
}}}
Again, ''os2dbg'' is the name of the pipe/socket specified in the !VirtualBox serial setup dialog.

{{{-h}}} specifies the number of lines for the scrollback buffer (history).
Scrolling in the terminal window requires to enter scroll mode: {{{Ctrl-a Esc}}}.

Off you go!
