Sigh.  I guess this is inevitable, but IMNSHO this exposes a weakness
in our serial subsystem.

The problem is that this means that a user has to know "oh, the serial
port on my computer is implemented with a Z85C30 chip, therefore it's
/dev/ttyPZ0 not /dev/ttyS0, like it would be if the designers had used
a 16C550".

Plus I'm sure this is going to mean that people using gui ppp dialers
on powermacs will suddenly find that the gui can no longer find their
serial port and they have no idea why.

Why should a user know or care about that?  It really should be "it's
the built-in serial port on my computer therefore it's /dev/ttyS0".

Paul.
