linux virtual terminals (ALT+F2 etc.) through conserver.

Hi folks,

With a screen and keyboard you can access the virtual terminals on a linux 
box by pressing ALT+F2 etc.

I'm assuming that this functionality is availble though the serial console 
also (perhaps a flawed assumption, I dont understand how or if linux maps 
tty[0-9] to the serial console.)

Assuming it is, does anyone know how to send ALT+F2 through conserver? Just 
pressing ALT+F2 unsurprisingly usualy causes something on my desktop to 
change, and I have tried adding various break sequences of (im still on 
conserver 7):
BREAK5=\00\151
BREAK6=\33\151
but this does not work.

Any advice would be much appreciated.

Thanks,
