# This script finds files in the /tmp  directory
#    The files have a name like x_mod_DTMF_NOTIFY, where x is one of A B or C, the local module
#    The contents of these files can be as follows:

# Example:  #        will unlink local module, "       U"
# Example:  B75703   will link local module to XRF757 C
# Example:  D00617   will link local module to DCS006 Q
# Example:  *00103   will link local module to REF001 C
# Example:  0 or 00  will report status of the link, "       I"

# We set this to spaces, it will be set later
