I did try enabling the powerbook's serial port in the Serial dialog box.
What I discovered is that the ppp-up doesn't actually hang the machine.
What it does is make the ppp script uninterruptable, so ^C or ^D or ^Z do
not stop it.  But if you're patient and wait for about 3-5 minutes, the ppp
script will give up, and will return the prompt after you press return.

The 500 series use a custom Apple chip, named Combo, that incorporates the
functionality of the 53C80 SCSI controller and the 85C30 SCC.
