dahdi-linux/pattest.c
Kinsey Moore 178ae27825 tools: Allow pattern tools to access channels above the device file limit
pattest and patgen already had this capability, but there were cases in which
they would act unexpectedly.  Now, if the name specified is not a character
device file, it will be treated as a channel number if possible.
