There is a call SerSetWakeupHandler or something (it is in the new
serial manager), that you can have it call your code when N characters
are received. You have to do a SersomethingPrime call to activate it.
It is in an interrupt so you have limited resources, but you can
enqueue key events. (I don't have the manual in front of me, but this
is where to look).
