[Qemu-devel] [Bug 1688231] Re: [Qemu-ppc] sendkey is not working for any of the keystrokes

[Daniel Henrique Barboza]

Yes, you are right: sendkey does not send keys to the serial console. I
had a chat with Peter last year about it in the IRC where the explained:

<danielhb> hey! quick question: is the 'sendkey' monitor command supposed to 
send the key presses to the serial console of the guest when running with 
-nographics ? The command works fine with VGA/VNC graphics but the serial 
console doesn't show the character key being sent by the command
<pm215> no, 'sendkey' sends a key to whatever physical keyboard is currently 
being emulated, regardless of what is being done with serial devices
<danielhb> pm215, I 've debugged the code and saw that the scancodes are being 
sent to the emulated keyboard via sendkey. I just wondered why the serial 
console doesn't show the keysyms but the VGA does
<pm215> because keyboards don't plug into serial terminals
<pm215> this is like having a server with a PC keyboard plugged into it and 
also a serial port which you're using as the serial terminal
<pm215> pressing a key on the PC keyboard doesn't do anything to the serial 
terminal
<danielhb> pm215, that makes sense, haven't thought of  that. thanks!

Given that the bug report was created around a wrong assumption, this
should be closed.
