Thanks for clarifying this. Looks like I need an alternate way to
access LPT2 through BASIC.  The docs with ProBAS (and presumably
PBCLONE) warn that this method may not work with spoolers, and
they were right.  PRTSWAP is probably only useful when two printers
are connected to the same machine.  Perhaps the spooler grabs the
port addresses when it first installs, and than PRTSWAP has no effect
because the spooler is unaware of the swap.  I'll try Port Finder,
just picked it up last week.

Does anyone know of a way to print to LPT2 on a network, where
LPT2 is a printer attached to the server?
