Aren't they voltages TTL level, not RS-232?  

I've been thinking for some time it would be handy to enable the mouse and
keyboard ports as generic serial ports under OpenBSD, so that I could
quickly interface to embedded projects (such as the webpal and recent GPS
modules) that speak TTL level '232 without having to tie on a MAX232.
