# Initialize or shutdown a PCMCIA parallel device
#
# The first argument should be either 'start' or 'stop'.  The second
# argument is the base name for the device.
#
# The script passes an extended device address to 'parallel.opts' in the
# ADDRESS variable, to retrieve device-specific configuration options.
# The address format is "scheme,socket,instance" where "scheme" is the
# PCMCIA configuration scheme, "socket" is the socket number, and
# "instance" is used to number multiple ports on a single card.
