# Purpose  : udev rules for the Yaesu FTX-1 via USB-C
#
# Preconditions:
# 1. Yaesu FTX-1 is selected via et-radio
# 2. Yaesu FTX-1 is connected via USB-C cable
#
# Postconditions:
# 1. /dev/et-cat created
# 2. /dev/et-audio created
# 3. rigctld is started
# 
# Note: As of 05/21/25 Yaesu has not published their CAT control command specification. This is a
#       temporary integration that does not include CAT control support. It will only key the PTT
#       and provide audio in/out. You MUST set the frequency and mode yourself.

# Special rule to ensure that the second serial interface (/dev/ttyUSB5) is tagged as ET_DEVICE=FTX-1 so
# that it can be used in the next CAT control rule.
