I'm trying to set the parity on the serial port of a LaserWriter,
and have run into trouble.

This is what I try:

serverdict begin 0 exitserver
%%[ exitserver: permanent state may be changed ]%%
statusdict begin 25 9600 64 setsccbatch
%%[ Error: invalidaccess; OffendingCommand: setsccbatch ]%%

Why on earth do I get an invalidaccess when within a exitserver context?
Experimenting reveals that this is the case for *all* operators
that change the persistent parameters, for example setdopage, 
setprintername, and so on.

If the password had been wrong, I should have gotten a
PasswordIncorrect error, so what on earth is causing the invalidaccess?

Help of any kind appreciated.
