X's serial drivers (in reality, all of X drivers) are modules for the MACH kernel. As such, most appear as UNIX devices in the /dev directory. Classic knows nothing about UNIX devices, so the abstraction layer that connects Classic to X translates classic driver calls to UNIX device accesses. This is why localtalk is dead in classic under X. Serial works fint because the UNIX serial devices were built to handle serial access, but they were not designed to handle localtalk, and the abstraction layer will ignore any atempt to access localtalk.
